Lionel made the statement i believe a few years before Mike R left. I will look for the thread/post. I may be mistaken, but i don't think so.
95% of all parts in stock- Not even close!!
Mike R was the one who put in all the time updating and inserting pictures.
(We all know what happened to Mike R, and all the good things that went with him.)
The parts listing for more recent items have never been updated/listed either.
Lionel doesn't "stock" parts except "staple items" They make so many, whats left over after assembly is used for warantee work, the rest sold off and are then gone.
Ironically. Lionels parts site is not working correctly. I get some sort of unsecured warning.
However, i know I can go on there and pull up a parts list for a 15+ year old loco and they will have 95% of the parts listed and available, except for something like the shell that says its at NLTW.
As far as parts on newer stuff. There is typically a long delay after the release until the parts are listed. This is probably due to the item still being under warranty as well as the parts lists are made when a production model is disassembled, and the parts are identified, numbered and listed.
There are no 'parts" made. All parts come from extra 'whole " locomotives that are "parted out" ,this takes time.
Having said all that, I totally agree with you as far as "Mike R. " is concerned, and I have ended new big ticket purchases from Lionel for that reason.
I don't think Lionels parts dept is dead just yet, but its likely beginning to wane
