Lilla will be one of the models getting a first run on Dduallt at an exhibition this weekend, having only been completed last year, long after the layout was last shown.
It's been used to give our slate waggon rake a test on the layout, here seen double heading with Moelwyn (one of my favourite models).
I'm told that Lilla is able to haul the full rake around the spiral unassisted, which is rather impressive for a very lightweight 3D printed body, I think.
The slate waggons are starting to show their age.
They're made from Dundas plastic kits and some of them are getting on for 30 years old, and inevitably that material starts to get brittle as it ages.
This is manifesting itself around the axle boxes which are the most vulnerable parts of the model.
Himself is taking about a rolling replacement programme for the fleet.
We shall see.
