hello, very nice mod, been looking after it a while and testing from time to time and i think it need 2 things :
- there is no difference which locomotive i use from bob mods (mk1,mk2,mk3 all same) and if i use armored loco (a lot better than other, more HP, more grid) it is also the same , only braking start faster , i guess cos its lot heavier...
- your fuel mechanic is great idea however it need balancing a lot more cos tons of other fuels bob/angel add and also mad clown which i also use ... currently trains runs faster on wood brick than on rocket boosters in my game , or faster on coke pellet than on coke which is same thing but compressed ... also there is some super fuels from mad clown with 4GJ , im pretty sure trains gonna go crazy on that with yours formula
EDIT: seems that (no matter fuel) max speed any train (modded or not) can get is little over 200 (so no personal transport with any train) - thats biggest problem i have with this overall nice mod atm :)
