Hello Kurt and Roger,
the rail and train rules are certainly buggy, but the next three
passenger trains will be faster at 50, 100, and 125 mph.
* The speed formula in VE "averages" rolling resistance and drag. In
edge cases like trains, it gives weird results.
* Coal consumption is too high and water consumption is ignored.
* I'm using a precedent from W:MP to "ignore" towing weight restrictions
for trains -- according to VE, each wagon would need HP 40 per ton of
load behind it.
I think David's next vehicle design book will fix this, but I wanted to
have the trains now.
Regards,
Onno

...but it was only hauling around 3,600 short tons rather than 12,000.
Maybe that makes the difference?
The Union Pacific Big Boy routinely pulled 8727 short tons over the
Wasatch Range...that's some pretty rugged country to pull that much
freight at 60+ MPH. But beyond the weight, if you look at the kW
rating for the engine and compare those, you have one that has X kW
and does ~25mph pulling Y mass, and then you have another has 2/3'ds
the kW, pulls 2/3'ds the mass, and yet does it three times faster.
