Engineers commissioning the new generation of software-enabled trains are

their train is computer controlled with its own software. This also has to
interface with the train’s third party software based systems.
I travel quite often on the new-fangled Siemens class 700 trains on
Thameslink, which are fitted with passenger information screens at intervals
in each carriage. Almost every day I travel I'm on a train where some or all
of these screens fail, most often going completely blank part-way through the
journey. Sometimes the screens spring back to life at City Thameslink or
Farringdon when the power source is changed and I guess some parts of the
system are rebooted, but not always. I wonder if the train companies are even
aware of these problems - there's no obvious way of reporting them.
At least thats not a show stopper, the trains can still be used. It seems
Siemens seem to have their ducks in line unlike Bombadier when it comes to
the important subsystems.
