Two-level coupler box

[smub]

Hi: I understand from this list that some Bachmann cars have two-level coupler boxes which make it possible to adjust the height of the coupler to match either Bachmann's HO scale height or the On2 scale height of couplers used by other On30 manufacturers. Apparently, the Bachmann steel hopper has the two-level coupler. I'd like to know what other Bachmann cars have the two-level coupler box.
Thanks.
