Skyfall is where we start

Popped to Leeds on't train today (of course....I wouldn't drive there!! :O) ....and spotted some train spotters on the far platform buzzing in their expectation of 'something'.  I thought of asking at the information desk if a special train was expected but my shopping list and time schedule overpowered me.
On return to my train home though, I spotted this LNER train about to leave for London.  Other that it being a Class 91 Locomotive built in 1988 I know nothing.....honest..........lovelupins aka 0050 something signing out.
