Today I got the 1404 EMT service from Derby to London (as far as Leicester) which departed on time.
At Trent South we were stopped because the 1345 from Nottingham to London had departed on time but somehow managed to lose 14 minutes by East Mids Parkway. We followed it to Leicester, chasing yellows, being stopped again at Loughborough and approaching Leicester Station.
At Leicester, the ex-Derby train was delayed further because a number of people thought it was the 1439 stopping service to London, they boarded and had to get off again when it was announced that it was non-stop to London. It left Leicester 15 minutes late and never recovered it's lost time.
The point is, the late running service from Nottingham could have been held at Trent to let the 1404 ex-Derby go first because there were no connections to speak of. However, they would have arrived at St. Pancras in the wrong order and probably cocked up the returning departures from there. The ex-Nottingham service just got later and later (according to RTT) and was almost 30 down by STP.
Should they have been regulated or was it a case of booked order rules!
