It’s a Locomotive on rails!

Features:

  • Two cylinders (single acting),
  • Crossheads,
  • Offset crankshaft for a better power stroke,
  • Wheel configuration: 2-6-2. Two leading wheels, six driven wheels, two trailing wheels.
  • Coupling on front and rear,
  • Eight blowers, slightly offset from each other to reduce the hammering effect of the thrust on the pistons, valves, conrods and crankshaft,
  • Valve cooling system,
  • Smoke generator (blocked jet engine pointing up),
  • Firebox with pseudo fire effect using Z-fighting (action group 0 toggles it),
  • Runs on rails. Doesn’t run without.
  • Max safe speed: 10.5 m/s.

Major update!

Changelog version 1.1:

  • Redesigned pistons, reduced part count and reduced lateral movement.

  • Redesigned crossheads to reduce friction, mass and remove lateral movement.

  • Reduced possible points of failure.

  • Improved bearing strength.

  • Improved valve timing a lot.

  • Slightly increased diameter of the driving wheels.

  • Added balancing weights to the crankshaft.

  • Added two blowers.

  • Top speed increased from an unstable, wobbling 3.2 m/s to a relatively stable 10.5 m/s.

Too many parts? You can reduce the length of the track, it’s 0.5km.

My first steam locomotive. There’s obviously room for improvement.

Instructions: just hit stage, throttle at 50%. Then gently throttle up as it increases speed to reduce risk of overheating the valves.

Note: there’s no reverse (yet).

Built in the SPH in KSP version 1.3.0.
