the return journey.

Why would Thameslink trains be sent up the ECML and cambridge line? Weren't
there enough free slots to test on the MML?

Part of the Thameslink Project includes direct services on the ECML
through Thameslink such as between Cambridge and Brighton and Peterborough
and Horsham.

The (closed) timetable consultation is at

I believe the junction is not functional yet, so they will have been
sent via WLL and North London Incline (the Gospel Oak Harringay route
being unelectrified).

Seems a bit premature to me... did they need to know the Foxton ballast
is a bit high so long before the services run? Wouldn't a diesel-hauled
gauging train with polystyrene shoes be better at this stage?

My understanding is that the Canal Tunnel route between Belle Isle and SPILL
is now open.
