This has reminded me of what I was told by an old railway engine driver on the Mid Hants. He told a number of us when discussing third rail electrification, that back in steam days he knew a member of footplate crew who peed from the engine...............onto the third rail!!
He died!!

As you may be aware, 2 of the loco owners I know have/had safety roles on the railway.
I know of at least one case of a loco failing on a section of track in scalectric country, the driver climbed down from the cab and was killed.
The cause was a failed earth return and hence the whole loco was live thanks to an un-fixed fault on the unit.
As for the idiots that are the general public, I encountered one the other weekend, As I was giving it full stick in the 47 heading north towards I spotted a family walking down the line!
We were the third train of the day as well so its not like it had been quiet!
Given we had 4 coaches, us, plus another 47 and a grid on the back.....it was a heavy train to!
