No such ban in place, you thought wrong!
I thought light engine kettle moves (in steam) had been banned by Network Rail following last year's disgraceful arson episode on the ECML involving Sir Lamiel and Oliver Cromwell.
Not at all! There was a ban on mainline steam usage of certain sections of the ECML on weekdays. (In fact it wasnt even that stark. There always was , and still is, a path out of Kings Cross for steam charters which can be used on certain conditions.)
Just recently I have seen Tornado at Kings Cross with a weekeday charter for York (check oput my flickr), 44932, 34067 Tangmere & 70013 Oliver Cromwell all passing MKC
What happened when parts of Yorkshire were "Set alight"?
We turned the heating off and took the chair outside,anything to save money
It was a light engine move from York to Southall with 70013 "Oliver Cromwell" and 30777 "Sir Lamiel" on September 2nd last year. The crew neglected to close the ash pan doors on "Sir Lamiel", so as you say it went on it's merry way depositing the contents of its' firebox down the ECML from York, causing grass fires along the lineside.There were (I think two) steam charters that had things left open (I forget exactly what now)
Long and short was hot materials that should have been kept in the engine were expelled into the line, and with it being rather hot and dry, subsequently set fire to copious amounts of lineside vegetation and ground the ECML to a complete halt!
