Unless I haven’t seen it, there should be a kelley blue book of train values on here…Type in your year model , condition , etc…and you get a ball park figure of what it is worth…
Buying and selling is not allowed on these forums, so there would be no point to doing this. What you may consider valuable other people may consider junk. E-Bay is where you need to be looking.
my bad…I was talking about for your own personal gratification not to sell or trade and if I had gold coins I would want to know how much they were worth and I wouldn’t go to ebay for that homes…
I, for one, understood what you meant. It’s really not a bad idea even if not everyone would use it. Methinks misunderstanding led to an unintentionally harsh reply. Just my 
(inflation)
thank you…didn’t mean any harm…
The trouble is, there would have to be someone actually assessing value. Kelley has an entire business of just doing that for cars. Greenburg does it for brass and there are a couple for Lionel if I’m not mistaken. Even these have yearly editions that come out with new values based on customer demand, current market value (which raises and lowers in different economies). It would be a monster to manage at the very least especially as you look across scales and manufacturers. As the first reply stated, eBay or other auction sites will be the best place to get some idea (maybe no the best) of the value of a model.

There should be but,it would be hard to do…
Some road names brings top dollars while others as no real resell value.
As a example I have a Arkon & Barberton Belt 50’ boxcar that I picked up at a show for $3.50.
According to a collector I know that car is worth $75.00.
He wasn’t sure who sold these cars or why but,they are extremely rare…
Now if someone could just do it for “cash”… I try to collect that whenever possible but it seems it keeps slipping in value and I keep having to trade more and more of it for the really valuable stuff-- you know, trains… [:)]

I’d rather have an online reference for engines and rolling stock. It would tell me when each type of car or loco went into service, and when the last of them went to the scrap yard.
If you like the Pennsy there is a lot of “all-time” roster information available online. Just go to google and type in “PRR all-time roster” and you’ll get a lot of sites offering information. Probably same for other major railroads. Another place to find information is Yahoo Groups. There’s probably a Yahoo Group for just about any railroad concern large or small. If not, start one yourself and see who joins. Another possible source is a historical society. Check around, in the area of the road in question, and see if someone’s put together a historical society to concentrate and disseminate information to interested parties.
