This is a Bristol & Exeter Pearson 9 feet 4-2-4T. This one will also work with a 1:1 replica of the entire valvegear system, it already has reached a top speed of 50 km/h during testing.

For the Bewilderbeast lovers here, i have good news, it is almost ready (this time really). I have finished most of the coding, and will move on to the final touches.
