ALCO / GE/ EMD
MDC fabricates a complete line of Alco/Bombardier exhaust manifolds and bellows connectors. Among them are 6, 8, 12, 16 and 18 cylinder 251-engine exhaust components. MDC is a supplier of exhaust components to the OEM.

We also furnish various other locomotive parts, from pistons, cylinder heads, machined parts, gears, and traction motors to gaskets, seals, hoses, cab parts and selected electrical components.
MDC also supplies a variety of parts for GE locomotives. We fabricate the dual pipe exhaust manifold for the 7FDL engine (transition section, main sections, bellows connectors, clamps, gaskets and end caps) as well as selected components for the older style, single and multi-pipe manifolds.
Just as with the Alco line, we distribute a variety of non-manufactured parts sourced from our trade partners.
For the EMD line of locomotive engines, MDC fabricates the exhaust expansion joints (both 10” and 14” dia, exhaust chambers and screens. And again, just as with the Alco and GE lines, we supply a variety of distributed parts.

Selected parts are also available for other engine brands, such as Caterpillar, Fairbanks Morse, Waukesha, etc.
