Golden Garratt

The only time we ever get to put the whole of Bron Hebog together is the rare occasions - a couple of times a year if we're lucky, when it gets invited to exhibitions.

If we've set up on the Friday evening the hour or so before the public get let in on the Saturday is our chance to have a little play for ourselves and so at the weekend our latest Garratt, 130, was taken for a spin around the S bends.

It's still very much in the running-in stage, with the front unit working much harder than the rear, and its test run came to a premature conclusion when the back one went on strike at the station throat.

I'm confident it won't be anything too serious.
