a piece of string is about this long....... USA trains F units, AB, 2% grade, 6 USA freight cars plus lighted caboose, 3.7 amps on DCC 20v on the track. If you are going to MU be prepared for 10 amp boosters or higher (serious mu, like 5 or more locos) What's the purpose of the question? Maybe let us know what your goal in a consist is? Regards, Greg
