Not to pile on, but it seems to me a QC issue across the board, please examine the following purchases and issues I found, ALL NEW RIGHT OUT OF THE BOX:
Train 1 - September 2014:
MTH PS3 LIRR MU had binded gears right out of the box
Train 2 - September 2014:
MTH PS3 LIRR MU was the dealer replacement for Train 1 above, and only had one truck powered.
Train 3 - September 2014:
MTH PS3 LIRR MU was the dealer replacement for Train 2 above, it runs...but has some funky quirks
Train 4 - Sepetember 2014
Lionel TMCC SP SD40-2's, both took some work by the dealer for the lead unit and myself for the trailing unit to work without hitch.
Train 5 - November 2014
Lionel Legacy WP F3, no grease on gears, totally dry, A-Unit engine, motor or gears...not sure is a little noisy, door found fallen off of B-Unit in box, reverse performance on lead A-unit and trailing A-unit (unpowered) is poor, i.e. derailment on a straight track.
Lead A-unit is wobbly. Oversized traction tires affecting performance as they rub against the truckframe/brake shoes...thanks lionel...
Train 6 - November 2014
Lionel PWC F3 TX SP A Unit, took this out of the box only for the 2nd time, and it will not respond to commands.
First time right out of the box, the power units lead truck had the engine mount screw fall out and I had to loc-tite it back in.
