The city actually gave us permission for this and promised us there "probably" wasn't any trains using the track that day.
This was actually the first time we'd ever tried to fit the train wheels, we didn't realise they wouldn't fit over the brakes, so we had to do some disassembly to make them fit :p
Here's where the barriers came down and we panicked a little bit as we couldn't figure out how to get them back up :)
