Numerous tidbit questions

After some time of no questions and comments only, RailPics did me in:

  1. Of all the high horsepower units offered in the 1970s, which do you think was the most liked by crews/mechanics and most reliable?
    I don’t mind seeing single units or combos . . .

  2. Everytime I see either a cab unit or a cowl units, I wonder if there are any interior photos, i.e. in the cab and in the engine rooms.
    I never seem to see or find enough photos of the interiors. But the exteriors look nice.

  3. Has north american railroad locomotive manufacturers tried to combine AC induction motors w/ locos, or are they already doing that?
    I know the DB inW. Germany tried it out in the 70’s and 80’s.

  4. On the cab units and cowl units and DDA40X’s (and Milwaukee’s Little Joes) , did the front door lead into the cab or just access certain cabinets?

  5. Did anyone try to put the toilets as a separate unit (like an isolated cab) behind the locomotive cab or not, was it ever feasible?
    ( I read the forum on toilets, but it didn’t cover this part)

  6. I’ll see what I can . . . actually is CSX in the process of upgrading their signals in Central FL or state wide . . . I’ve started to see the new 3/2 light systems . . .

  7. Did anyone try liquid cooling for a traction motor?
    I know it sounds dumb . . .

  8. I’ll try and come up w/ some more questions . . .

Thanks [swg]

  1. SD40-2

  2. There is one on tales of the krug.com. Here is the link

  3. Not practicle

Wow that was fast . . .

hmmm . . .

I wonder when the other members will come up . . .

Both GE and EMD have offered A/C traction motors since the late 80s,

Nose doors lead into the cabs, with equipment on either side of the isle.

On the Wide cab units, the toilet is on one or the other side on the isle.
Some of the older full cowl units; toilet was in back, enclosed in the engine compartment.

Liquid cooling for traction motors isn’t not practical, adds systems that require extensive maintenance.
Air cooling works, is cheap, and requires fewer parts.

I just remembered a question: what does the isolation switch do?

Also there was a case in Trains where the lead unit was put isolation . . . what does that do?

And another . . . this time from read “Tales from the Krug” . . .

Did the trough train do well in service, or not? And what are the details to strange piece of equipment?

Is that round thing on the side of the nose the hatch for the toilet? If not then what is it?

No it is not. I am not sure of what it is though.

2.: If you mean F units, I have quite a few photo’s of engine room and cab photo’s.

I got some pictures of the inside of WSOR 10A or 10C, whichever one was in Janesville WI for the roundhouse anniversary. Unfortunately I don’t know exactly where they are at this time…

Isolation switch does just that, isolates that locomotives control stand electrically from the locomotive, you can move the throttle, reverser and such, and nothing happens.
Also isolates the locomotive out of a MU consist.
Round thing, I assume you mean the toilet air vent.

I think the UP built a separate “outhouse” on the rear of one of its SD40-2s once, making use of all of that extra porch space. Don’t know what happened to it, but it obviously wasn’t worth repeating.

Well I read about that one, but what I was thinking about was it ever feasible to make the toilet “room” a separate unit i.e. modular unit like dynamic brake modules . . .
