Looking at e.g. https://www.youtube.com/watch?v=S9k7XvFH3pE there
isn't a lot of DC track out in the open away from the fenced off

track (about 5:12) which is rather more than usually seen at
transition points.


We will have to disagree about what “isn’t a lot is “ .

Quoting from this website.

http://www.old-dalby.com/operation.htm

“This line is now electrified with 750v DC conductor rails for
approximately 3 miles and the SSL trains are based in the compound during
the daily testing. The yard sidings at the former control centre have also
been equipped. Power for the DC line is routed from the sub-station at
Asfordby. All other functions are now conducted from the new complex at
Asfordby, and the SSL trains travel to and from Asfordby each day, hauled
by a diesel locomotive.”


Given we have Old Dalby in the UK why do so many new trains do their testing
in the Czech Republic these days? Perhaps there's an argument for one track
to be returned to being a regular railway linking Melton Mowbray and Nottingham?



For a start, Velim is circular, so it allows continuous testing at high
speeds, rather than changing ends every few minutes. It's got OLE
throughout (rather than only for a few miles of Old Dalby) compatible with
all major European systems, so presumably all the manufacturers already
have a contract there; in which case it makes sense to utilise the one you
already know.
