It should be given to the BTP rail cops
No it shouldn't ! - It's a valuable assett and if Cleveland no longer need it then it should be SOLD
to the highest bidder to recover some of the revenue spent operating it.
As for BTP, with all the National and Regional collaboration going on,
it
might be more cost effective if BTP stopped hiring the "old squirell",
which they try to cover their vast rail Network with, and instead negotiate
agreements with the Police forces through whose areas the rail tracks run,
to provide Air Support / patrols as and when needed.
