I've purchased several Lionel switches recently, and the last 3 (O36 x 1, and O48 x 2) have arrived with problems. One O48 jams mechanically, one O48 will only throw one direction, and the O36 would only throw via the "anti-derail" function. The replacement O36 has already arrived and works. Have yet to return the O48s.
These problems exist via remote, LCS, and in the case of the mechanical jam -- even manually it can't be thrown.
Am I just unlucky? First four I purchased work like a champ. Next 4, not so much.
