Over here since the dawn of time 1 or 2 catalogue companies in a bid to cash in on the hobby have done their own train sets or packs or sometimes loco's. Some are rare, some are rubbish, now they have settled for doing a loco and 3 coaches. usually at full whack price but still cheaper than buying seperate. Trouble is you can't always tell what you're getting for definite. Last years grey A4 came with the old type gresley coaches, no one knew for definite until they got hold of one.
