Cundupa, Flyingvan911 is right. We'd see the NS power in Roseville occasionally and the long hoods were the leading end. They were SD-45s if I remember but unlike our SP power, both the long and short ends were high hood-- maybe for a steam generator?.
If I remember correctly; some were even dual control... engineer's control stand on both sides of the cab.
Roseville was a great yard to work and we had motive power from all over through the shops. Alcos (I date back to the era of the PAs). When I made my date, our yard switchers were the old turbo-charged 6-cylinder Baldwins. Took the turbos about 20 car lengths on a hard pull to wind up but when they did You knew you were sitting on some power.
Had a fleet of EMD SWs in "cow and calf" configurations for hump engines.
The commuter fleet off the peninsula ran Fairbanks-Morse Trainmasters, running big inlines with 2 pistons and two crankshafts per cylinder. The pistons met in the middle of the cylinder bore and each was the other's cylinder head.
We tried the Krauss-Maffei (sp?) diesel-hydraulics (both first and second generation) and burnt the transmissions out of all of them since they didn't like slow, heavy trains and that's what the SP was fond of running. Our last one had the nose compartment modified into a camera platform and was pushed around, filming track footage to be used in the locomotive simulator.
Had all three Alco diesel-hydraulics which spent most of their time on the ground... too heavy and rigid for our light (60 and 75 pound rail in some places), poorly maintained yard tracks.
Some (I think they were Alcos) had air start systems that fired a charge of compressed air into the first cylinders on each bank. Always took you by surprise 'cause they sounded like a howitzer with a silencer.
Then there were the first-generation radio-control locomotives...
There did we use them? --as helper power on the mountain.
What's wrong with R/C helpers? --these were pretty much line-of-sight comm. links.
What does the mountain have? --lots of curves, dips and rises, and, oh yeah... tunnels and snow sheds.
As a result; our let's-cut-off-crews-and-save-a-bunch-of-money remote operation, radio-control locomotives all had their very own engineer who's job it was to hit the override button whenever the helper locomotves didn't pick up a command and kept shoving when the head-end was trying to stop, or kept braking when the head-end was trying to get the train started up the next incline.
We tried both slugs and "B-units".
Our long trains (we tried 2+ miles long but couldn't get the brakes to release-- too much leakage) brought on the need for enough air to keep the brakes working so the company tried "repeater cars". These were modified boxcars that had 3-71 Detroits turning big three cylinder Worthington air compressors to keep the trainline charged.
I think the CMO in The City (#1 Market Street, San Francisco) figured we were a test bed for locomotives 'cause we sure had some odd ones.
With the mountain (Donner Summit to the east), a long straight run to LA via Fresno and Bakersfield to the south, The bay area to the west and a combination of flat and mountain territory to the north; we had all kinds of railroad to throw at them.
