There is no mention any where of a freight train nearly setting back into 1D44
Train manager I spoke to on a St Pancras to East Midlands Parkway service that I travelled on later same day said the chaos at St Pancras and down route involved a freight train as well as an EMT service somewhere just north of Leicester (Sileby).
From a passenger perspective it wasn't good though - even six hours after the incident none of the EMT staff at St Pancras or onboard trains had any real idea what was going on in terms of the ongoing running of services. At St Pancras staff were largely telling people to get on a train going north even if it wasn't going where they wanted and telling them to hope there was a connection further down the route, one staff member at St Pancras recommended I go to Kings Cross and get a train to Grantham even though by the time I'd have got to Grantham there'd have been no trains to Nottingham let alone to East Midlands Parkway, there were buses taking passengers from Leicester to Loughborough and East Midlands Parkway at the same as there were delayed trains running (thus wasting passengers time on slow buses), station staff at Leicester (even at 22:30) were clueless about how passengers should go forward from there or what time there might be trains (I got more / better information from the web and from the UK Trains iPhone app than I did from staff), and the buses were held to wait for more passengers for 20 minutes when there were no further trains arriving within that period! I ended being told to take a bus from Leicester to East Midlands Parkway via Loughborough, only to find a later train coming from London had planned stops at Leicester and Loughborough and East Midlands Parkway, and had comfortably beaten the bus to East Midlands Parkway.
Honestly, I think everyone else accepts that investigations have to take place and that means normality might not be resumed as quickly as we might hope, but six hours later??? I don't necessarily expect normality in that timeframe but I think it's reasonable to expect the TOC to have come up with a plan and to have communicated it to all front-line staff in that time. The railway - EMT in this case - still have to lot of work to do to make sure that passengers are managed in the best possible way when the wheels come off the wagon.

PS: Even though I spent quite a while talking to the train manager, he didn't cancel my ticket and barriers were open at St Pancras. Train manager said delay repay wouldn't apply because it wasn't EMT's fault (really???)... So I guess I could consider reusing my open ticket another day as a self-administered delay-repay!!

[JOKE!!! before anyone gets a sense of humour failure about that]
