Any chance you could do "Locomotion" I love "Puffing Billy" with all those cranks in motion.

Nice, how about Great Easterns 0-10-0T decapod??

can you make a castle class locomotive?

It (and all the others you have uploaded today) look really nice (shame I can't play tpf2 yet (either have to wait for when they release the Apple version or until my old PC is fixed) also if you are intrested in semi obscure or nonstandard locomotives take a look at the Mr 2501 (granted more than just one was made I find it quite neat that it was built by an american company (Baldwin) and strayed quite a bit from British practice at the time (1899) but its up to you really merely a suggestion

Been hoping to see this one turn up - thanks Steve. My great uncle and grandad used to work at Bromsgrove Carriage and Wagonworks and worked on Bertha from time to time. They remembered her as this hulking great black leviathan with the massive searchlight lighting up everything around at night.

Good work! it seems you have a smooth-shading issue on the firebox however. As a blender user, I would rectify it by adding an 'Edge Split Modifier' to the firebox object, however I'm not sure which software you use. Other than that, its great, keep it up! :)

What an early Christmas! Great to see more awesome British stock. Keep up the awesome work!

I shall proceed to sing "Big Bertha" by Dave Goulder now throughout the time I use the good lady in the game. Thanks for the new engines Steve! Great job as always!

that cylinder tho
