I forget how much the EMD sumps hold but I believe it's a couple hundred gallons.....and they just add a 5 now and then... I do know that between the crank throws and the bottom of the oil pan, it's at least 2 feet. Don't know what they use either but knowing the railroad, probably the cheap stuff. I do know they don't run antifreeze, they run plain water and if the temp is below freezing and they get shut down the cooling water automatically dumps.
Used to haul cranks to EMD in McCook, Illinois and I spent a lot of time watching them build locomotives and engines.
Interesting that the EMD engines are all steel plate weldments and each block segment is a V8, 4 cylinders (power packs on each side) and multiples of the primary segment make up the bigger engines. The cranks all bolt together as do the cam shafts. Each one has a companion flange on each end. They could build as large an engine as a customer wanted. Kept adding on block segments.
I believe they are no longer there, but it was a great experience for me. I went there twice a week usually.
When waiting for an empty trailer (the trailers that carried the cranks and cams were dedicated trailers, open tops with a canvas cover with specially made wooden racks inside that the cranks and cams rode in so I dropped a full trailer and picked up an empty, I used to wait by the siding that they dyno tested the engines on.
If you look on the side of and EMD engine, midway above the fuel tank, on the right side, there is a large rectangular shaped cover. Under that cover is a male plug. That is where you plug in to test the engine / alternator output. They ran a huge thick extension cord from that plug to a water cooled resistor bank and they'd run the engines up to rated rpm (I think about 1200) and then put the resistance bank to the alternator at maximum draw. Sitting next to an engine putting out maximum amperage, you could feel the ground vibrate and there was fire coming out the exhaust stack. The sheer power they make would give me goose bumps and it was amazing to watch them blow fire. Like having the engine in notch 8 but not moving.......
They build all the engine components there, from the compound gear drive turbo's to the power packs and I always enjoyed walking through the factory and watching them build engines. They had overhead cranes in there that could pick up an entire locomotive and move it across the shop. Amazing place. I was there so often, I could walk the shop and no one bothered me. Put on my EMD hardhat and safety glasses. Had a nice lunchroom too. Always ate my lunch there.
Pretty familiar with locomotive engines.
I get a kick out of guys fretting over their 50 hour oil change. The oil never got changed in those engines.
Had a big dyno room where they 'blew them up' too.
