C-liners took many of their design cues from the Erie-builts, and appeared in the F-M catalogue with a variety of options.
All freight units, and the CLC-built Model CPA/B-16-4 were designed with a B-B wheel arrangement, while passenger units (in addition to having different gearing) featured an unusual B-A1A wheel configuration, as the rear truck required an extra unpowered axle to help distribute the weight of the steam generator.
