How did the thieves know where they were?
I heard that the train was stopped unexpectedly - meaning it was an opportunistic theft, not something planned - and that much of the stuff was later found discarded, I guess by thieves who realised that what they'd nicked couldn't be sold. Stand down, paranoiacs.
The rumour locally is that there was a report of a body on the line, and the signal controlling the entrance to Bank Quay Station was changed to red. It was at this time that the theft took place, apparently.
About 12 boxes were stolen, but only three or four were taken away apparently. If I was choosing a place to rob anything off a train, this would not be my choice. Next to the line at this point is a Royal Mail sorting office and a number of industrial units, all of which are surrounded by high fencing.
Robberies from trains are, to the best of my knowledge, unusual. If the IRA was still around, I'd say it carries all their hallmarks. I haven't got a tinfoil hat, but I won't be around the Warrington area on Nov 5th
