Great job to all involved, I adore this route.

- One question though: the manual section about firing the B4D says:
The Scripted Automatic Fireman: This is available to users with certain limitations:
1. The built-in auto fireman must be off.
2. The F4 HUD must not be used.
3. F3 Display can be used without impact
--
Level 0 - The script does nothing allowing for one of the other firing options to control. If the built-in auto fireman or the use of the F5HUD is detected, the script will shut down if it has not already been set to zero.
If I'm reading this section correctly, then neither F4 or F5 HUDs work with the scripted fireman. If that's the case, how do we watch the engine's operating info if we're not in the cab? F3 HUD isn't very helpful for operating a steam locomotive.
Unless I'm reading this wrong?
