About the AX Series

Designed for versatility and mobility, the AX Series is at the forefront of modern in-motion train weighing systems.

The unit can be conveniently taken to the train in a vehicle, removing the need for the train to travel to a static weigh station. The AX Series is instantly ready to use with high accuracy calibration, which is permanently stored in the units memory.

Its self testing capabilities ensures the highest levels of precision when weighing locomotives and wagons, regardless of sizes, number of wheels of axles. All combinations are accommodated. Axle overloads and NETT weights are automatically weighed and stored along with Gross weight, tare weights along with other information.

The AX Series will:

  • Ensure all product weights are correct for delivery to your customer
  • Improve safety
  • Highlight any wheel imbalance problems
  • Assist prevention in derailment
  • Prevent increased wear to rail vehicles and infrastructure
  • Eliminate wheel flat spots and brake lock ups
  • Increase fuel economy
  • Ensure symmetrical loading and highlight any off centre loading

Here at TrainWeigh, we are constantly striving to enhance Rail and Passenger safety. From measuring the centre of gravity of trains to detecting levels of equilibrium. Our systems offer high-speed weighing prior to bridge crossing, ensuring that trains meet and exceed the world's highest regulatory standards.

These achievements allow us to supply the highest accuracy for weighing of goods. We have systems that also benefit from OIML Trade requirements, for most countries in the World.


AX systems are ideal for train manufacturing workshops, testing Locomotives, Bogies and Coaches when building from new, repairing or general maintenance. Single or multiple units can be used for highest accuracy.


AX train scales can be used dynamically, collecting individual wheel weights and summing the total train weight, this is ideal for goods and freight trains. Automatic weighing ensures correct wheel, axle, wagon and total train loadings and weight distribution.

Features of the AX Series

The AX Series comes with a host of technology to ensure accuracy and consistent high performance.

Weight Indicator & Ticket Printer

The Heavy Duty IP67-rated Pelicase weighing terminal boots up in seconds.

On-board 14.4 mAh battery gives you 10 hours of practical use on a single charge with a battery level display on the front panel.

The touch screen indicator has a user friendly interface whilst being capable of in-depth functions with multiple programmable parameters.

The indicator gives your results in real time, recording individual wheel weights, axle weights, wagon weights and the total train weights.

An 80mm thermal printer is also built into the case to give instant weighing results on hand. Any imbalances will be automatically detected and alert the operator on screen and on the printed tickets.

All the data can be imported into our PC software for more detailed analysis and easy archiving to .csv or .xlsx formats through the on-board USB and Ethernet data ports.

Static Weighing AX Software

Multiple scales can be used to weigh a full static vehicle instead of individual axles. The screenshots below show the types of data available using our AX software with multiple units. Up to six AX's can be combined into a single system.

Dynamic / Static Bogie Weighing (DPS) Derailment Protection System

The DPS is an unmanned or manned system that can identify individual wheel loadings. The system will raise an alarm if any wheels or axles are out of a pre-set tolerance input by the user.

Health and Safety is optimised with the DPS’ built in Centre of Gravity system. This makes identifying load errors, wheel and suspension faults quick and simple prior to trains leaving the depot. The DPS System is especially useful for providing peace of mind that the train, carriages and cargo are safe.

All data can be stored internally on the DPS for downloading to a PC or USB stick and/or printed for records of the readings to be signed off and stored for future reference. The recorded data can easily be integrated into ISO quality systems.
