Converting Lionel's latest 21" Passenger Cars to 2 Rail

In the past I have converted several sets of the Lionel cars using MTH 2-Rail streamline trucks which are an excellent copy of the Lionel truck side frames, plus they have scale 36" wheels and are equipped for 2 rail electrical pickup for the car's lighting system. The Lionel LED system will work on DC and DCC electrical power as well. Total cost of the MTH trucks is probably less than the cost of replacement scale wheel sets and the scratch building of electrical pickups. Kadee couplers fit by using a spacer for installation and with the car disassembled for conversion I also do a bit of interior paint work and add 1:48 or 1:50 seated passengers and a few standing passengers as well. Take you time on the first car as the others will be a repeat of the process. Using this process you can always trade or sell the Lionel 3 rail trucks to you 3 rail friends. Gene

Correct me if I'm wrong, but aren't these Ex K-Line tooling cars? Could one simply use the K-Line 2 rail trucks? I see those on e-Bay often. Just a thought.
