Much as I love all the Isle of Man railways, number 18 "Ailsa" is in any eyes, pug ugly. Built for work on the London Underground as a contractors loco, it was never meant to be seen much above ground. Moved to the island in 2000 to help with laying a pipeline under the railway, it transferred into the fleet as a shunter.
Unusually, it ran the length of the line months ago, hauling a couple of steam locos to the place they were going to be stripped of asbestos. This video shows that train in operation.
It also provides plenty of views of this ugly duckling. Handy, because it's so ugly, I'd really like to model it. There are already a lot of photos in my collection, I just need a plan (and some time).
