Hello, I have just received two Kato SD70 ACE heritage Loco's. I have the weight numbers for rolling stock, but not for Locomotives. Does anyone have this info. If so has anyone try to add weight to these, there is no room under the shell. The only place seems to be in the fuel tank. But the tank is molded to the lowerrail . Any suggestions :confused:

Actually, there are no weight standards or RP's, (recommended practices) from the NMRA. I guess they felt that due to all the different sizes of locomotives in all the scales it would be impossible and unnecessary.


In my experience you just want to have as much weight as possible in a locomotive. Wherever you can cram in another fleck of lead do it.
