Given Awdry was quite keen on accuracy to the real world engines (see the falling out with one of the first artists) I’m actually surprised there isn’t more consistency with the liveries. The Culdee Fell Railway has all engines with the same purple livery, and I think from memory the steam trains on the Skarloey Railway are red, which is more accurate to real life as generally each railway would have its own livery.

I think earlier on when there were fewer engines it was less of a problem as they all had fairly distinct shapes being based on different real engine classes Garden and pre rebuild Henry probably being the least distinct.

You were supposed to bring order to the railway not cause confusion and delay

They need more content to keep their animation team busy.

You’d think it would be Surf.

Would be a nice thing to have in the spec for the cable, as those ones aren’t compliant with the spec, and can in some cases cause problems, like on disconnect it might be possible for one of the PD pins to short against one of the data pins before the side delivering power has had time to process the disconnect.

It’s a pretty specific edge case and I’m sure not a problem most people have had or will run into, but would be nice if it could be part of the spec.
