I am sure this topic came up before, but I’ve been searching the forums and I can’t find anything on it. So here it is: how do you start a diesel locomotive? I know how all of the controls operate and all once you’re started, (thanks to MS Train Sim among other sources) but how do you start it? Is it a keystart like a car, or is it some thing more complicated?
first you have to make sure that all the electrical circet brakers and switchs that will alow it to start are on…(im not telling which ones and where they are)…
and then you have to find the start station…now you have to make sure that the safty rests are not triped… if eveything is good…you move the start swtich to prime for 30 seconds…and then to start to start it cranking… if she donts want to trun over while cranking…you grab the layshaft lever and and give her some more fuel…and it “should” start…lol

whats a petcock? lol
well yea…they still have them…but the majority of prime movers come with auto drain equipment that will drain the cylinders…i have never used a petcock in the 7 years i have been in engin service… hell…i dont even know nor was ever showed how to drain a cylinder with a petcock…

Many of the engines on the CP are equiped with ‘Smart Start’. The system is designed for fuel conservation. The engines start automatically when the water temp gets below a certain level (to prevent freezing). In warmer months, the engines ‘time out’ and shut themselves down. During shutdown, a warning bell sounds in the cab. If the reverser is not moved in a certain amount of seconds, the diesel stops. MU’d units operated the same way. It can get verrrrry quiet all of a sudden. Neater yet is running the lead unit in the consist at idle. All controls function, lights , heat and ac work, but the diesel isn’t under load (cut out). Makes for a very quiet and nice ride. Usually though, a train has too few engines, not too many. Some smart start systems allow the engineer to start the engine by simply putting the reverser in forward. The engine (engines) spring to life , the conductor yells “HIGHBALL’” and the engineer replies "HERE WE GO! Then the folks in the cab get to experience the thrill of anywhere between three thousand and 20 thousand horses getting thirteen thousand tons of steel and grain rolling down the rails! This is one of those few moments when yes, you should be jealous of those who do this for a living!
yes we have the same type of system on many csx engins now too…the K9 APU units…but many of them have the auto start with the reverser disabled now…so you have to still go out and start them manualy if the APU shuts it down…
alot of the new power…mostly EMD 70 and 80 macs and im guessing the 90macs have it built in from the factory… also they have a push button in cab starter…no need to go out on the catwalk to find a start station…now all the GEs i have been on…have a maunal start station outside the cab…some other roads might have an in cab start station…but i have never seen it…

Do the diesel-electrics have glow plugs? I know once it gets around or below freezing, you just leave them running to keep everything from freezing up, but just curious.
Newer NS Locomotives have autostart too, such as selected Dash 9’s and SD70M’s. There will be a sticker on the cab saying autostart equipped. I read where CSX was going to install something like a ‘pony engine’ on some of its fleet. It would serve to keep the oil and water warm on the main prime-mover. A number of years ago,my father bought an old Caterpillar crawler/dozer with a 4 cylinder diesel engine with a small 2 cylinder gas engine as the starter. You rope start the pony motor…it warms the coolant and cylinders of the diesel, then you engage a clutch to use the pony to start the diesel…In the case of the concept on Locomotives, it does all of the above except start the primemover, just keeps it warm.

csx already has it… its the K9 APU unit… and its just that…a small engin that runs to keep the water warm…and the battery charged up… should it get so cold out that it cant keep the water warm on its own…it will start the main prime mover and alow it to run untill the water is at a preset temp setting…and then it shuts the prime mover down agin… and takes over…this prosses will keep on going untill the unit is started and used for service…or untill the APU faults out…and dumps the water to protect the prime mover…
csx engineer
Thanks…thats what I thought…I do remember reading that it was also meant as a fuel savings, the APU would use a few quarts to a gallon an hour instead of the 5 gallons an hour the main prime mover would use were it kept idling. Dave Williams http://groups.yahoo.com/group/nsaltoonajohnstown
i might add that once you get the engin started you need to insert the reversing lever its shaped like a key on the end opposit the handle… on a verry rare ocaccion i have seen one engin jump start another with electric cables from cab to cab becouse the batteries were dead…glennbob p.s. i do have a photo of one bn engin jump starting the other from a parrall track>>
On the subject of petcocks, most large diesel engines I worked on in the Navy have indicator cocks on each cylinder which were opened before starting and the engine cranked over while someone watched for coolant discharge. Any disharge would result in a repair job. If nothing was seen the cocks were closed and the engine started.
This same indicator cocks were used at about 400 hour cycles to measure cylinder firing pressure using a Kline Pressure Guage at near full load and RPM, results were recorded for maintenance histroy.
on the subject of petcocks the white superrior 8 cylinder in line has a snifter valve port on the side of each cylinder to attach a bacaratt firing pressure tester… this is used when the engin is running>>> also this save is true of emd engins this test shows the actual firing pressure exerted at each cylinder and is an indication of fuel metering
In the mid 1990’s, my poppa and I went on a motoring trip from Munich through Austria to Slovenia. We get to the rental garage, and I find we have a Fiat hatchback. OooooooohNoooooooo! Actually, for all the bad tales of Fiats in the American market, this one is pretty nice and quiet with firm seats. And it is a turbo Diesel! Oh, fun! (Oh, save some Deutsche Marks on fuel on account of the German trucking lobby and the higher tax on gasoline).
I get in and turn the key. R-rer-rer-rer-rer! Nothing. Try it again. R-rer-rer-rer-rer-rer. I am starting to sweat. The rental car guy didn’t tell us anything about a trick to this car. And then, a distant memory of having worked 20 years earlier at an auto company on a direct-cylinder fuel injection project as an electrical engineer, and all of the things my automotive-engineer boss told me about Diesels. Ah, glow plugs! Turn the key part way to get the red glow plug indicator, wait for red indicator light to go out (mind you I had no instructions on this, if it weren’t for my stint at a car company, I would be another dumb American tourist draining the battery trying to start that car), turn the key, and vroom!
Now I was not a complete Diesel neophyte. My poppa has an IH Diesel tractor (50 HP) for his orchard which I have run many an hour doing chores for him, and there are no glow plugs. You move a level to change the injector advance, crank, it catches, a little black puff of smoke, a little rough running, move the injector advance to the run position, put it in gear and pull out of the shed. I got training on this procedure and have done it for years.
What’s the difference? The IH is a DI (direct-injection) Diesel as are just about most truck engines, locomotives, and bigger stuff. The Fiat was an IDI (indirect-injection) Diesel. It has a combustion prechamber which requires a glow plug for starting. It has more complete combustion under heavy load, so there is less sm
