thanks the decoder information is good to know, i soon i will have enough information that i can make an informed decision on how and what i am going to do.  But for now  i will just keep looking

thanks Gary

thanks for the response, had a quick look at you tube the ones i seen show an install different decoders thru out but none show the how it all finishes just the finished result not how they got there, thats what i need to know but thanks for the help so far, i will go thru you tube again and see if i missed one but so far a lot of them are the single motor. 

Have a Great and Safe Day

i have 3 Spectrum 44 ton The Master Switchers, two of them are brand new still in the box from years gone by, and the 3rd has seen better days anyway i was wondering what decoder i could put in these units sound or not, but i cant seem to find out what these units draw for amperage and having two motors and trucks in them i thinking there maybe a problem since there is limited space. So help here would be greatly appreciated
