:o ;D
It would be very funny to play with, I think. But a bit absurd. And small - train drivers are possibly going to overlook it... :D
The sidetrack was not in use. Police just stopped it, because it crossed roads. Some spoilsorts alerted them. It was not even an offence just "unauthorized using of railway tracks". Might be still expensive, becasue they might have to pay for the helicopter flight.
(Then an offence would have been cheaper.)
So they should have driven naked to make it an offence? :D
Not even sure this would have worked. Maybe rather a false allegation as political statement ... ?
