Did it once. Got lost, thanks to a controller back at the depot trying to be helpful and giving me an alternative route.
My trusty steed refused to engage reverse at the previous station, leading to me grinding to a halt midway through a three point turn on the forecourt. Eventually some SWT managers pushed and we got some backwards motion. The next stop was in the middle of nowhere and also needed some shunting around, I didn't fancy getting stuck so got on the radio, but rather then send me another motor I was given some, ahem, 'directions'

"Straight under the viaduct, not left?".... "Yes". Actually no, it was left. And so we had an entertining quarter of an hour or so bouncing through some country lanes in a low floor bus with no reverse, waiting to get wedged somewhere or for the inevitable tractor to come the other way; thankfully all I got was a couple of locals in 4x4s looking very surprised to see me coming towards them! I think it was probably the only time country sorts in 4x4s have moved out of somebody else's way
