Ahead of Railtex 2022, Thales has announced the introduction of the Mk4 Single Cab Control Unit of its Train Protection and Warning System (TPWS).
The new unit is compact in size, and can be retrofitted to the Mk1 and Mk3 systems to deliver major enhancements through a simple, time-saving, and cost-efficient upgrade.
Easy to fit and run with existing systems in both single and dual cabs, there is no need to change anything underneath the vehicle and ensures interoperability with the European Train Control System (ETCS).
TPWS Mk4 recognises lines where ETCS is fitted and takes over as the priority safety system where ETCS is not fitted. It provides a protection and warning system with built-in suppression and un-suppression so that it can automatically recognise and adapt depending on the signalling system on the line.
The new system offers a host of additional features which will benefit train operators, train builders, and rolling stock companies, including:
- a more-compact system for Single Cab Installation as the Mk4 Control Unit has been reduced to fit the same footprint as the existing Mk1/Mk3 Control Units, whilst the Single Cab Control Unit has removed the need for a connector in the second cab to save space;
- a future-proof solution as it paves the way to both ETCS and RBLS. With both single and dual cab options, Thales TPWS Mk4 delivers a high degree of safety for the digital railway and provides In-Service Testing advocated by the Office of Rail and Road (ORR).
- no configuration is required when installing or replacing the TPWS Mk4 equipment. All that is needed is a routine proof test and the vehicle is ready to enter service.
Tristian Crawshaw, Head of Product Sales at Thales Ground Transportation Systems, said:
“TPWS has served the industry well for over 20 years, and we are excited to announce this latest upgrade to enhance and continue its safety record. The new solution is designed for ease of use and made for the future of rail.”
