OK, thanks for the tips.

What astonishes me is that the the webstore on the Bachmann homepage doesn't specify which couplers will be on the product that you will receive when you order online.

Surprise!
Surpirse!

Also the rolling stock cars, not just the locos. Are they Rapido?

When buying Bachmann locos (steam or diesel) are Rapido couplers installed or some other type?

Incredible as it seems, the online Bachmann catalog does not list which type of couplers are on the product! Why they do not is perhaps merely indifference to being helpful to customers.
