I experienced about a five minute delay at Euston Square Inner Road this morning around 7am. Seemed like a communication issue to me as a passenger sitting in the middle of the train. Doors were shut and lights off but every time the train seemed like it was going to move off, it didn't. This happened three or four times, then the driver made and announcement and presumably must have reset something, and we moved off.
There was an S8 train at Euston Square this morning with door issues that was taken out of service with the door interlocks cut out to obtain forward movement.
It was reversed via Moorgate bay roads to be sent to Neasden depot but upon arrival back at Euston Square the signalling system didn't seem to allow the train to proceed in automatic mode. After some trial and error in consultation with the train technition at Hammersmith control centre, movement was eventually established in protected manual.
manorborn , Whilst we still have temporary migration areas there is always going to be a liability for teething issues to occur when trains switch over systems. That liability increases given the dominance of computer based control systems in the railway environs.
At an LURS meeting this week, it was commented on that there is a known deficit of radiowave coverage in certain locations that could be responsible for trains dropping out of the system going non-communicating (Baker St in recent days). Whilst it’s still safely within tolerances, it’s obviously noticeable enough to warrant remedial action.

Whilat there are a few problems at Baker Street the section giving the most trouble is between Royal Oak and Paddington - there are modifications being commissioned this weekend to try and address the issue.
The radio coverage is intended to be 400% for reliability purposes.
