I've been contemplating buying a 2850 pack for a while. I know the coaches are basic but I like the E04, and I know they can be improved with closer coupling and extended gangways.

One thing though - should both coaches in the pack have the same running number, and is that the same as the number on 4136? Obviously I want to make sure I get a pack with the right items in, but all the ones I've seen so far have the same number on both coaches which seems a bit odd to me.
