Freight: Lineas targets cost-effective ETCS
Europe’s largest independent freight operator Lineas has decided to equip its diesel locomotives with a new generation of software-based ETCS onboard equipment being developed by The Signalling Company.
Earlier this year, a Class 77 diesel locomotive belonging to Belgian freight operator Lineas returned to regular operation on the national network sporting a new cabinet of electronic equipment ahead of its cab. Retrofitted with a range of off-the-shelf components, it is acting as a guinea-pig for the development of a new generation of software-enabled ETCS equipment.

Wasn't an issue for freight that every sixth wagon had to have a device fitted for train length purposes?
There already must be lots of such systems available, after all the SBB managed to retrofit ETCS to a bunch of older locos (e.g. Re 4/4, Re 6/6, and the NPZ - and the BLS also upgraded some of their Re 425 which are similar age). The SBB have sourced the hardware from all of Bombardier, Alstom and Siemens - it's hard to imagine that it's going to be a complete ripoff with the existing competition.This system might be for an open access freight operator, but perhaps it could be useful for retrofitting older multiple units? Even those that were sold as few years ago as ETCS ready, the ETCS hardware they were intended to accommodate might no longer be available or superseded.
