That must be the reason for going so far from London! Otherwise I
would have thought that, say, Aylesbury - Claydon would involve far
less haulage.

The stock is being built by Bombardier in Derby, so by using Old Dalby it
can be commissioned whilst on delivery.


Aylesbury to Claydon is also not electrified at all.

While Old Dalby is currently (excuse the pun) NR 25 kV AC and Movias
need LU 660 VDC, the grid feeder substation and switching gear will
already be in place, along with linseside fencing to latest standards
and so on. Its rather simpler to convert an already existing
electrification from one to another sytem even if they are very
different.
