We stock it
We're a stocking distributor, not a broker. The fast-moving numbers are on our shelves, which is why a quote on in-stock product goes back to you the same day.
We make it when nobody else will
When a part goes obsolete or hard to find, we have it manufactured. Several parts we now sell under the JMC name started exactly that way.
We rebuild it
We rebuild water pumps, blowers and HLPs in house — so a core coming off your unit has somewhere to go.
Carbon is where we go deepest
Brushes are among the most replaced items on a locomotive, and the choice drives how the whole machine performs. We match the brush to the application by grade, wafer and shunt — and stock the holders and spring clips to go with it.
Our stock brushes have historically shown the lowest dusting of any brush on the market.
