Thanks , you guys are too kind . ;D
All 4 of the MP-54's are powered with TM-05's .
The length of the wheelbase looks close enough for me , I didn't bother measuring because of the pleasing enough looks . The ends of the TN-05 are extended with the ends of the chassis/floor/step piece supplied with the kit . If you look over at Atlas's forum and do a search under " Island Modelworks " , all threads of all the cars I have built so far will be there including this MP-54 Powered conversion . If you click onto my Trainboard Album under my name below ( A new feature I populated just yesterday , and will still grow it ) there are photos of each LIRR Modelworks kit I have done so far , but little if any text .
Yes the MP-70's double deckers are finished in 2 schemes .
