Liter has a question for anyone with Z scale experience:

“My current Z scale engines and rolling stock all have Marklin type couplers. Unless you purchase Marklin equipment, these couplers seem to be unavailable from other suppliers. For example, Micro Trains and AZL seem to have there own types of couplers. My question is: How many kinds of couplers are there and how can I be sure the new pieces of non-Marklin equipment I might buy have compatible couplers?”
