On Track Plant Identification Guide

On Track Plant Indentification Guide

This page gives a guide to identifying on track plant and track machines on the UK rail network. Track machines in the UK are often allocated their own headcode which pairs up with their individual track machine number. The below table lists track machine numbers, and their associated headcode.

This page is useful for identifying track machines. If you have spotted a track machine and know the headcode but not the train number, or the train number and not the headcode, you can identify it here.

Rail Record will tell you which services are tampers, grinders etc. If it shows operator Balfour Beatty, Harsco, or has a trailing / timing load of “715 tonnes”, it will probably be a track machine. Another way you can identify a Track Machine is by its service code. If you use a different website for live train times such as RTT, copy the service code and use the Rail Record list of Train Service Codes, accessible from the main menu.

The above track machine identification guide is correct as of July 2018. If you spot any mistakes or would like to recommend changes to the Rail Record track machine identification guide, please use the Get In Touch page.
