As there seems to be no reply to this (I post via googlegroups, so
they may not be visible yet), I'll put in some words here.

The "Police" loco is just a run of the mill loco (class 47, if you're
interested), with no direct connection with any police force. It was
painted in that livery as part of a campaign against route crime
(vandalism and the like).



So basically they thought driving a train around with the word POLICE on
it would stop crime on rail routes? Why wouldn't the criminals just run
away from the track? *waves fist*
