The German language news bulletin about the railway scene in Germany, Austria and Switzerland has just made a
report of the upcoming revolution in digitalised shunting, which I suppose was inevitable.
The plan, apparently, is to make
Scharfenberg couplers standard on all freight wagons and locomotives and replace the screw couplers used at the moment. The reason for this is that screw couplers require someone to hook them up and connect brakes and electrical connections too, which takes time and is very dangerous, whereas a Scharfenberg coupler theoretically can do all this at once and also report back to confirm everything works. On European railways we still use lots of marshalling yards, and apparently a shunter can couple or uncouple wagons up to 300 times a shift.
The project aims are:
Refit about 490 000 freight wagons in the EU, Switzerland, Norway and the UK, and 17 000 locomotives
The projected cost is expected to be 15000 - 17000 € per wagon.
The cost throughout Europe should be 6.4 -8.6 billion euro.
Savings are reputed to be in the region of 760m euro per year.
Added to this is the massive improvement in safety, as many shunters are injured in their work, and the Scharfenberg coupler will allow for longer trains.
There is currently a demonstrator train being tried out in various conditions. If the test go to plan the project should begin in 2024 and end by 2030.
