One of the least spotted vehicles on the Isle of Man is the National Air Traffic Services (NATS) railcar.
Normally hidden away, it come into its own transporting personnel up the mountain when the Snaefell Mountain Railway isn't operating.
A couple of years ago, the railcar went to Claytons Rail Services for a refit and there and I managed to visit and take a huge selection of photos with a view to building a model. This hasn't happened yet, but if you fancy the challenge, these pictures will help.
