Do parts in the parts catalog ever get restocked?

[sedfred]

 I need an ho scale overland limited tender shell (my kitty had his way with it) but it is not in stock. It has been that way for months and months and i want one but they never seem to restock anything in the parts store. Why is this? It's always good to make sure they are always in stock, you can't just leave us hanging! So i'm wondering will it get restocked at some point?

Dear Sedfred,
We usually get a number of parts when an item is re-run.
this will likely be the case here as well.
Have fun!
