Diesel Steam-Electric Train Mk4

Description
Price: $75000
Fuel Consumption: 0.1 L/s to 0.4 L/s
Effective Range: 300-1000 km
Horsepower: 380
Max Torque: 5000 kN

For horsepower, SW doesn't have realistic weights and physics so 380 is a LOT. Add another 0 for real-world equivalent. This is calculated using the sWatt for stormworks, which pretty much just divides by 10.


SLIPPAGE:
· for heavy loads you must use the slug, since apparently the Stormworks have never played games like Derail Valley and dont understand how Tractive Effort works. The more weight on the train does not increase slip resistance unlike real life. I've done all the lovely tests and researched it, sadly.


Variations:
Version with Slug
Large Diesel-Electric Version, 10k Cheaper, 10x less fuel efficient, 0.8x same power
Slug

This Multi-Role Diesel Steam-Electric Train has many features, including:

· 10ATM Brake Pipe for other cars
· 4 Large Steam Pistons
· Hot exhaust that can go to 1000 Celcius is gathered and used at 40-60 ATM to improve fuel efficiency.
· ABS Braking for individual Brakes
· Automatic Low and High speed gearing for the large electric motors
· Horizontal Suspension for curves
· Can share power with slugs.
· High-speed flaps, for above 50 m/s to improve slippage. Above 50m/s it might be better to just use a prop or jet engine. Could also just slap a turbopropeller on the top and power it with the large electric motors. Slippage be real.
·· Slug speed control is on radio channel 687.35
· Proprietary knuckle that shares power, brake pipe and Traction Motor power. TM is blue, brake is red, power is green. Most rail cars seem to kind of fall into the same Y-axis range of the 2 battery power knuckles, but others have different knuckle designs.


Mk1 and Mk2 were bad designs, they did not look nearly as good and had massive wind drag.




TODO:
· Add controllers for the horizontal track suspension so they automatically center, otherwise the entire train is off-kilter from the track. Not high prio because it functions just fine without it.

Checked:
· does heat-exchanging the used up steam with the water before the boiler pre-warm the boiler water? (Just like how exhaust is also hot)
· YES. Pre-warmed water improves boiler efficiency.


New Things to check:
· Can you just put the entire water tank on the same cooling loop as the steam boiler to 'pre-heat' all of the water even before the boiler gets to it? (Not something you can do IRL, but maybe a possibility)

Things to check with boilers:
· does heat-exchanging the used up steam with the water before the boiler pre-warm the boiler water? (Just like how exhaust is also hot)
· could you also use exhaust alongside warming up the boiler to warm up the water tanks?
· does creating a vacuum in the engine compartment effect heat efficiency?

Other possible versions:
· Turboprop on top, dont use a jet engine, but have a medium turbine + turboprop.
· Small Ducted fans for above 80m/s to improve speed. With the rails, 70m/s is already very precarious, especially with cars that like to explode.

Note:
· Speed is not the objective, but it is always fun to have other versions for the multi-role position.
