Bill and the crew are away on their holidays at the moment, but I'm certain that when they get back they will be very interested in putting together a rail bicycle so they can get around the tramway quickly if they need to.
This readily available dollshouse miniature bicycle could be a useful starting point.
My Mum was heavily into dollshouse miniatures, but mostly 1/12th and I still have three of her houses here at home. I was almost tempted into building a tramway in 1/12th, but there simply isn't enough space for it. I'm sure Mum had a bicycle somewhere in her bits boxes so I must have a look for it. Most bicycles sold as 1/12th are underscale so I'm hoping that I can find it. If I remember correctly it was red which Bill and the crew with love, coz as everybody knows red ones go faster
