Google the original part numbers, or look them up on parts dealers' websites. For MPC/Fundimensions parts, many parts have the added the "600" prefix, but only by Lionel.
This was done to be able to track parts electronically, so all parts have a 10 digit number. Old part number 8xxx-3 becomes 600-8xxx-003, for example, and then it follows - 8xxx-20 becomes 600-8xxx-020 and so forth. Changes that use a part which has been superseded appear to not follow this due to the substitution.
