Correct MB. I shall post another pic of the second loco later when I open it's box. I'm planning on converting that one into a tank engine with no coal wagon if possible as I have plans for it ...
SB - correct ish. I am liking the monitor look an awful lot but am not sure if I should box the roof in. I like the curve.
Cardboard underskirt and first piece of plasticard. The card is one bit. I partially slit through it enough to let if fold neatly and used this as a former as I've no bits of wood lying about. It seemed the easiest thing to do.

Armour plate on. The funnel, light and armoured dome (lego bits and plasticard) are not attached but I wanted to see how it looked. Also unsure about the funnel. Too wild west? Should the funnel come off?

I am planning inspection ports too but need to think about the cab armour. I removed the battery compartment without realising that it had the rear coupling attached to it and it's impossible to get back in now I've started. Appropriate hole in plasticard methinks.
