Railway Communication Solution: Choose the Right Radio for Every Railway Team

 

At 2:00 a.m., the railway is quiet.

The passengers are gone, but the railway is not.

A track maintenance team is working several kilometers away from the station. An electrical crew is checking equipment beside the line. A supervisor is moving between work areas, while a service vehicle is carrying tools to another section.

Then one team needs help.

The supervisor needs to reach them immediately.

But what if there is no mobile signal?

What if the existing analog radios only cover part of the working area?

And what if the railway company does not want to replace hundreds of radios that are still working?

These are the real questions behind a railway communication project.

There is no single radio that is best for every railway worker. A station employee, a remote track maintenance team and a regional supervisor can have completely different communication requirements.

A better approach is to match the radio system to the team, working area and available network.

 

Six Communication Options for Railway Teams

KANGLONG provides several radio technologies that can be used for different railway applications:

 

DMR | LoRa Mesh | 4G PoC | High-Power Analog | Standard-Power Analog | Dual-Mode

 

The choice depends mainly on three things:

• Where the team works

• Whether a network is available

• Whether the customer already has an existing radio system

 

1. DMR — Professional Communication for Local Railway Teams

DMR is a practical choice for railway teams that need organized professional voice communication within a defined area.

 

Track maintenance, engineering, security and railway yard teams can be assigned separate channels or groups.

 

For example:

• Channel 1 — Track Maintenance

• Channel 2 — Electrical / Signal

• Channel 3 — Inspection

• Channel 4 — Supervisor

 

If direct handheld coverage is not enough, a DMR repeater can be added.

DMR is particularly suitable for railway operators that already have a digital radio infrastructure or need structured group communication.

Recommended: DM-800

The DM-800 is an IP68 DMR handheld designed for demanding outdoor work. It can be considered for track maintenance, engineering, security and other professional railway teams.

The key advantage is straightforward: workers can communicate quickly without depending on a cellular network.

 

 

 

 

2. LoRa Mesh — When There Is No Cellular Network

Some railway sections have a different problem:

 

There is simply no network.

 

A remote track may have no reliable 4G signal. A temporary maintenance area may be far from existing communication infrastructure. Tunnels, mountains and heavy concrete structures can also make conventional communication difficult.

 

This is where KANGLONG LoRa Mesh can be considered.

 

It is designed as an independent, self-organizing communication network. It does not require a SIM card, cellular network or Wi-Fi.

 

Compatible LoRa radios automatically form a mesh network, and each device can also work as a relay. Signals can jump from device to device by up to 30 levels. When the direct signal becomes weak, the system can automatically forward the communication through another available node.

 

For example:

Radio A → Radio B → Radio C → Radio D → Radio E

The communication does not depend only on the direct distance between A and E.

 

 

 

For larger or more difficult areas, dedicated repeaters can be added.

• D6000 — 20W fixed/vehicle repeater

• D6000R — portable 18W repeater with battery

• D7000 — 20W solar-powered repeater for permanent off-grid deployment

• D6000E — 18W mobile repeater

 

These repeaters can help extend the LoRa Mesh network in remote railway sections. 

Recommended: D750 + D6000/D6000R

The D750 is an 8W IP68 LoRa Mesh handheld with 30-level relay capability.

For a temporary railway maintenance project, a D6000R can be positioned as a portable relay.

For a permanent remote railway section, a D7000 solar repeater can be considered.

 

Important: The KANGLONG LoRa system is independent from DMR and analog radio systems. LoRa products communicate with compatible LoRa products; they do not directly communicate with DMR or conventional analog walkie-talkies.

 

3. 4G PoC — Wide-Area Communication Without a Local Repeater

A railway supervisor may need to communicate with teams at different stations or across a large region.

This is where 4G PoC becomes useful.

 

PoC radios use the cellular network for push-to-talk communication, so users are not limited by the coverage of a local radio repeater.

Typical users include:

• Regional supervisors

• Operations managers

• Maintenance managers

• Mobile service teams

• Contractors

• Teams working across multiple railway sites

 

But there is another option that can help reduce the operating cost of PoC.

Wi-Fi PoC — No SIM Card When Wi-Fi Is Available

Some KANGLONG PoC models, including the G320, G360 and Android PZ-56, support Wi-Fi.

 

This means that when workers are in a location with reliable Wi-Fi, the radio can connect directly to Wi-Fi instead of using a SIM card for cellular data.

 

For example, Wi-Fi may already be available in:

• Railway stations

• Control rooms

• Maintenance offices

• Warehouses

• Depots

• Workshops

• Railway terminals

 

In these areas, users can use the PoC platform through Wi-Fi without consuming a mobile SIM data connection.

This can reduce the number of SIM cards required and help lower recurring communication costs.

The G320 and G360 are compact Wi-Fi/4G PoC radios, while the Android PZ-56 supports Wi-Fi, Bluetooth, GPS and Android-based applications.

Recommended: G320 / G360 / PZ-56

For railway personnel who regularly move between Wi-Fi-covered buildings and outdoor areas, these models can be particularly practical.

Wi-Fi available → connect directly to Wi-Fi.

Outside Wi-Fi coverage → use 4G with SIM.

This gives the customer more flexibility instead of relying entirely on mobile data.

 

4. High-Power Analog — 10–20W for Traditional Long-Range Communication

Some railway customers do not need DMR or a network-based communication platform.

They simply want a conventional analog radio with higher transmit power.

For large outdoor working areas, a 10–20W analog radio can be considered, subject to local frequency regulations and licensing requirements.

Typical applications include:

• Large railway yards

• Track maintenance

• Outdoor engineering

• Construction sections

• Maintenance vehicles

Recommended: T-930

The T-930 is a 20W analog radio designed for users who want traditional high-power radio communication.

It can be considered when the customer's priority is simple, direct radio communication rather than a digital or cellular platform.

Higher power does not automatically mean longer real-world coverage, however. Antenna position, terrain, frequency, buildings and interference also affect the result.

 

5. Standard-Power Analog — Simple Communication for Shorter Working Areas 

Not every railway team needs 10W or 20W.

Station staff, small maintenance teams, warehouses and railway yards may only need communication within a relatively defined area.

For these users, a conventional 5W or lower analog radio can be enough.

It is simple, familiar and does not require a subscription platform.

Recommended: P-500

The P-500 is a 5W analog radio designed for professional field communication.

For railway teams that mainly need straightforward group or point-to-point voice communication, this can be a more economical choice than deploying a more complicated system.

 

6. Dual-Mode — Connect PoC With the Customer's Existing Analog Radios 

This is particularly important for railway customers that already have a large analog radio fleet.

Replacing hundreds of existing radios simply to introduce PoC can be expensive.

 

A better approach may be to use a dual-mode radio with a transfer/repeater function.

The radio can work with:

4G PoC + VHF/UHF Analog

 

More importantly, the dual-mode system can be configured to link the PoC side with the customer's existing analog radio system.

 

For example:

PoC Radio → Dual-Mode Radio → Existing Analog Radios

A supervisor using PoC can communicate with workers who are still carrying their existing analog walkie-talkies.

This means the customer does not necessarily need to replace the entire analog fleet at once.

It can significantly reduce the investment required for upgrading the communication system.

Recommended: PG-60 / PG-66

The PG-60 and PG-66 are dual-mode PoC/analog radios.

They support 4G PoC and VHF/UHF analog communication, and the dual-mode platform includes a repeater/transfer mode for linking the two communication sides. The PG-66 also supports frequency matching with existing analog radios, which can make fleet upgrades easier. 

This is a particularly useful option for railway customers that already have hundreds of analog radios in service.

Match the Radio to the Railway Team

Instead of asking:

“Which radio is the best?”

Start with:

“What does this team need to do?”

 

 

Example: One Railway, Different Communication Systems

Imagine a railway operator with three different working environments.

 

Station

Station staff and security personnel mainly work inside a defined area.

A 5W analog or DMR radio may be sufficient.

Where Wi-Fi is already available, a Wi-Fi-enabled PoC radio can communicate through the existing Wi-Fi network without requiring a SIM card.

 

Remote Track Maintenance

A maintenance team is working 10–20 km away from the station.

There is little or no cellular coverage.

Instead of installing a cellular network, a LoRa Mesh system can be deployed.

The workers carry D750 radios, while D6000R or D6000 repeaters can be positioned where additional coverage is needed.

The radios automatically relay communication through the mesh network.

 

Regional Supervisor

The supervisor needs to communicate with teams in different railway locations.

A PoC radio is more suitable where 4G coverage is available.

If the supervisor is inside a Wi-Fi-covered office or station, a Wi-Fi-enabled PoC model can connect through Wi-Fi instead of using mobile data.

 

Existing Analog Maintenance Team

Another group already has a large fleet of analog radios.

The railway operator does not want to replace them immediately.

A PG-60 or PG-66 dual-mode radio can be introduced as a bridge between the PoC system and the existing analog communication network.

This allows the customer to upgrade communication capabilities without replacing every existing radio at once.

 

Which System Should You Choose?

Choose DMR when:

• Professional digital voice communication is required

• The railway has an existing DMR system

• Local group communication is the main requirement

• Repeater infrastructure can be installed

 

Choose LoRa Mesh when:

• There is no cellular network

• An independent communication network is required

• The railway section is remote

• Long-distance communication is needed

• Users can form a mesh through compatible LoRa radios

• Repeaters can be added for greater coverage

 

Choose 4G PoC when:

• Teams are spread across different locations

• 4G coverage is available

• Wide-area push-to-talk is required

• The customer wants centralized communication

 

Choose Wi-Fi PoC when:

• Workers are frequently inside Wi-Fi-covered areas

• The customer wants to reduce SIM usage

• Railway stations, offices or depots already have Wi-Fi

 

Choose High-Power Analog when:

• The customer wants traditional analog communication

• A large outdoor coverage area is required

• 10–20W power is appropriate for the application

Choose Standard Analog when:

• Communication distances are relatively short

• The customer wants a simple and economical radio

• No digital or cellular platform is required

 

Choose Dual Mode when:

• The customer already owns analog radios

• The customer wants to introduce PoC

• Replacing the entire radio fleet would be expensive

• PoC users need to communicate with existing analog users

 

Which system is best for a railway project?

 

There is no single answer.

DMR — professional local digital voice communication.

LoRa Mesh — independent long-range communication where there is no network.

4G PoC — wide-area communication where cellular coverage is available.

Wi-Fi PoC — PoC communication through existing Wi-Fi, helping reduce SIM usage.

High-power Analog — traditional 10–20W communication for suitable outdoor applications.

Standard Analog — simple communication for smaller working areas.

Dual Mode — connect PoC with an existing analog fleet and reduce upgrade costs.

 

The best configuration depends on the railway team's location, coverage requirement, existing equipment and available network.

 

Build the Railway Communication System Around the Team

A railway operator does not have to put every employee on the same radio.

A station team may only need a 5W analog radio.

A track maintenance team in a no-signal area may need LoRa Mesh.

A regional supervisor may need 4G PoC.

A railway office with Wi-Fi can use Wi-Fi-enabled PoC radios and reduce SIM usage.

A customer with hundreds of existing analog radios can use dual-mode radios to connect the old system with PoC instead of replacing everything.

 

That is the practical way to design a railway communication system:

Look at where the team works, what network is available, what radios are already in use, and how far communication needs to reach. Then choose the technology.

KANGLONG can provide DMR, LoRa Mesh, 4G/Wi-Fi PoC, analog and dual-mode radios for different railway communication requirements.

FAQ

• Can D6000E communicate with DMR or analog radios?

D6000E belongs to the KANGLONG LoRa Mesh system and communicates with compatible LoRa products.

It does not directly communicate with DMR or conventional analog walkie-talkies.

 

• Does the LoRa Mesh system need a SIM card or cellular network?

KANGLONG's LoRa Mesh system is designed for independent communication without cellular networks, SIM cards or monthly cellular data fees.

Compatible devices form the mesh network themselves, with each node able to participate in signal forwarding. 

 

• How does LoRa Mesh extend the communication range?

Compatible devices can act as relay nodes.

The system supports up to 30 levels of relay jumping, allowing communication to travel through multiple devices when a direct connection is not possible. Dedicated repeaters such as D6000, D6000R and D7000 can also be used to extend coverage.

 

• Can G320, G360 and PZ-56 work without a SIM card?

Yes, when a suitable Wi-Fi network is available.

These Wi-Fi-enabled PoC models can connect directly to Wi-Fi and use the PoC platform without relying on a SIM card for that connection.

This can be useful in railway stations, offices, depots, workshops and other locations where Wi-Fi is already available.

 

• Can the same PoC radio use Wi-Fi and 4G?

Yes.

For Wi-Fi-enabled models, Wi-Fi can be used when the radio is within a suitable Wi-Fi network, while 4G can be used when cellular connectivity is required.

This gives the customer more flexibility and can reduce SIM/data usage in Wi-Fi-covered areas.

 

• Can a dual-mode radio connect PoC users with existing analog radios?

Yes.

The dual-mode system can use its transfer/repeater function to connect the PoC communication side with compatible existing analog radios.

For a railway operator with a large analog fleet, this can reduce the need to replace all existing radios during a PoC upgrade.

 

• Does the customer need to replace all existing analog radios to introduce PoC?

Not necessarily.

A dual-mode solution such as PG-60 or PG-66 can be used to connect the PoC side with the existing analog communication system.

This allows the customer to upgrade the network gradually instead of replacing the entire fleet immediately. 

 

• Is a 20W analog radio always better than a 5W radio?

Transmit power is only one factor.

Terrain, antenna position, frequency, buildings and interference can have a major effect on actual coverage.

A 5W radio may be sufficient for a station or yard, while a higher-power radio may be more appropriate for a large outdoor maintenance area.
