I have had a lionchief + NYC hudson since christmas. Out of the box the front pilot axle was loose. Charles Ro sent me a replacement pilot. Otherwise never a problem and it runs like a top and my son runs it constantly.
Just ordered the LC+ NH rectifier on pre-order from Nassau
My only complaint would be having to wait for Lionel to offer LC+ in the next road name or loco that appeals to me...if they are listening (which i doubt)B&M GP9, NH EP5, PRR GG1 in brunswick, maybe a B&A berk or a NYC F series.
