Proof of attention to detail - Lamp codes and maintenance work
Say what you like about bouncing chassis or child VAs, I think even just in this singular frame of the trailer there's a lot of respect for railway realism.
Gordon has his express headcode (two lamps), and Thomas has his branch line headcode (just one), and with the maintenance going on to gordon, it might actually feel like the human workers on the railway actually have something to do beyond just stand inside an engines cab and be useless.
Mind you, both these engines should have 'light engine' headcodes right now (one lamp on top of smokebox) but still, I think it really looks like they've done their research and made something that's going to be a happy medium for all fans young and old, new and returning
