very rare vs rare vs htf trains

I too passed on ALL re-editions Donald, douglas & hank. we should keep these and any others on a separate list to be fine tuned at a later time. hard working diesel, however, is a train that could be considered very rare. hard to say, right now with limited data. but if you have 1 or can get 1... I would. I have mentioned these trains before & would like feedback. pop-out peter sam and mavis.
