Even though we've worked for 20 years to create a layout of very ambitious scale, one which is also as accurate as we can make it, we're not above having a little fun with what we run on Bron Hebog at exhibitions.
We've always quite enjoyed making a cheeky reference to the politics of the railway or happenings, such as the model of the crashed car at Bron Hebog crossing which - as I expected - was a talking point at weekend among those 'in the know' who came to look at the layout.
Another irresistible target was the appearance of the replica Lynton and Barnstaple Baldwin Lyn at the Superpower event, which was appearing on the Welsh Highland for the weekend under the strict understanding that it would never been seen near the FR's resident Manning Wardle Lyd.
(That moment is to happen for the first time in Devon.)
With Himself having burned some midnight oil to get our new Backwoods Lyn to the stage where it can run the temptation was too great...
The model itself is still requires a lot of running in, producing a rather dramatic squeal if given too much juice, and it still has a rather pronounced waddle at this stage, but it managed to put in a few laps of the layout, some of which were caught on camera.
The real loco was only running top and tail with Taliesin between Caernarfon and Waunfawr, and we had the chance to take a ride behind it courtesy of the free Rover tickets which the railway provided for all exhibitors.
Ours ventured a little further south to Beddgelert.
We will, of course, post updates as construction is completed.
