Thanks, that was interesting. From the conversation, the 4th rail test
track is 4km long, and includes virtual stations and virtual tunnels. The
train has to do 500 miles (800km) of testing, so a 100 cycles.


One thing that strikes me from the various videos of the old Dalby test
route is that it is mainly straight. As more trains like the S stock get
constructed with full width connections between cars
or even articulations that could be an achilles heel.
The law of sod if you are testing something says it will be the bit that
wasn’t stressed that shows up an unexpected snag .

Obviously the S stock has been in service long enough now around the LU
system that they must have got it right in that case but there will be
other stock in the future.

I see plans for the Welsh based Global Centre For Rail Excellence were
recently published
and like the test tracks in the Czech Republic and Germany will have a
continuous circuit available.
so it could give Old Dalby competition .
