I would like to propose an expansion for the rail based content, perhaps in a similar way to the weapons DLC for certain parts.
More rail parts:
- Single Axles, 3 axle bogies, 4 axle bogies.
- Different sized wheels, this will enable some more realistic designs which use different sized leading and trailing wheels to the driving wheels.
- Steam pistons and connecting rods that can connect to the end of axles, maybe have them dynamically connected similar to tracks.
- Steam Whistle.
- 3rd rail connection points for pulling electricity, maybe charged for usage at a rate.
- More exhaust/inlet options, see various funnels and relief devices found on different locos around the UK.
- Steam powered pumps.
- Different types of signals, maybe add some semaphore signals somewhere.
- Hand valves as an alternative to using pushbuttons and toggle buttons.
- Alternative levers to use as throttle replacements. Such as winding handles and reverser levers.
- Slightly different windows, similar to port holes but with bars on them. Pretty common in the UK.
Expansion to the rail network:
- Better loading spots on the network, maybe more including fuel as fuel could be interesting to transport around.
- Passenger missions using stations. This could be a good way to make money, such as replace the previous service and take the 20 passengers from that station to another.
- Better size of load and unloading facilities, especially for coal, maybe have longer coal drops and gantry's to drive under for loading.
- More tracks, covering more of the island, and not always double tracks either. Ensure some passing loops exist for swapping the loco around although this isn't always needed.
- Single tracks to places like the Dean Hall mining company, with some passing loops and a run around at the end.
- Single track to Sawyer south port, with passing loops.
- Not putting everything on bridges all the time.
- Marshalling yards at the ports, maybe with some overhead cranes to load and unload containers build onto them. This would give additional shunting tasks potentially due to the extra sidings.
- Maybe run some tracks along the dockside for easier transfer of cargo to and from ships.
