I have got to try the class 801 (800) and found some discrepancies. (and this old thread).

Diesel engine has correct power 700 kW, but electric has 4x 226 = 904 kW, according to

http://www.hitachi.com/rev/pdf/2014/r2014_10_105.pdfPower and weight is also here (for the whole train). Power agrees with the above.

Was there any specific reason? Comparing the weights of 5 and 9 car trains, it seems that all powered or unpowered cars have almost the same weight (difference less than 1 t).

Also the constrainsts and upgrades are not real. There is not composite trailer but a composite motor...

Also the above document states acceleration at 0,7 deccelration 1 m/s^2.

Brake_force is set to 49, which slightly higher, than my claculation: 46.60 kN for electric, and 48.60 kN for diesel. (But I think it should be the same). So 49 kN is OK.

tractive effort: electric 77 kN, my calculation for 5-car unit is 68 kN, 9-car unit 73 kN, soooo OK... (already with gear accounted for)

But for the diesel unit it seems too low (62 kN) - with 50% gear... Given the fact thet the traction motors are the same, just the power supply is limited, we could assume that the starting acceleration could be the same (maybe only for short while). Tractive effort for 9-car diesel unit and 0.7 m/s^2 is in my calculation 61.24 kN, but without gear. So to get the same acceleration we have to multiply by 2 -> 122 kN.

Also there is a clear typo in br800-rear fixed cost (+10000 compared to others). Also I don't understand why trailers have so high fixed cost compared to motor cars? Are there any approximate rules - how much are fixed costs of staff (driver, conductor, buffet) ?

As I have finished the electrostars I will continue with these.
