I just saw a GP-30 on the point of a mixed merchandise train going heading west through Gulfport, MS for New Orleans (Saturday 3/10-10:00 AM). It looked freshly re-painted in the current blue/yellow/grey scheme. I missed its number, it went by too fast. It could have been the GP-30 Slug that's been around for a while, but the last time I saw the Slug it was painted all grey. Also, why would CSX re-paint a GP-30, unless it was being donated to a display or museum? I will try to get its number if/when it comes back east. Has anyone else seen a re-painted GP-30? Hank
It was more than likely one of the road slugs that was rebuilt from a GP30. There were a bunch of those, not just one. Chris Toth
there are quite a few (2200-23??) but some numbers are vacant. there aren't very many that are in y/b/g scheme. I've seen some like that. most I've ever seen where gray with blue lettering, and yellow ends.
There are a fair number of the GP30 road slugs repainted into the newest CSX scheme, such as this unit (photo courtesy the CSX photo archives, credit to the photographer, as indicated): I think many were delivered in the stealth scheme, and just like anything else, they are repainting it as they get around to it!

That's an interesting photo. 2209 doesn't even look like a GP-30. It looks more like it started life as a GP-35 or GP-38(?), with a straight hood line continuing over the cab. The unit I saw on Saturday had the heavy brow over the cab that was the classic identifier for the GP-30's. I'm still waiting for that Slug to return from Gentilly Yard (NO) to get its number. Of course it could have come through during the night, or when I wasn't looking Later, Hank [ 12 March 2001: Message edited by: Hank Coolidge ]

Good Grief - I never realized CSX had THAT MANY slugs .... OK, now for my next dumb question! Why would the Ops Dept. want a large roster of slugs? It's my understanding that slugs consist only of four traction motors and a whole bunch of cement for weight in place of the prime mover. To use a slug, you need a full-blown loco coupled directly to the slug so the loco can also supply juice for the slug motors. Obviously you can NOT run a slug alone for this reason. Also, I assume that the loco would need all of its juice for its own traction motors when under heavy load. Sounds like slugs would have very limited useage. I can understand hump or yard duty, but as road engines .... ? I'm sure it must make money or else CSX wouldn't do it. Anybody have some insight?

the CSX slugs, have prime movers I think. they have a smaller prime mover (hence n ot side door for access to the motor), but the tractive effort is a lot more after their conversions to slugs. yes they are used as road engines ***[the part about the slugs having smaller prime movers, is because 1, it makes sence, and 2, I was beside on one day that was hooked up to an SD40-2, the SD40-2 was shut down but I could feel the het radiating off the side of the unit, and the vibrations (not to mention the noise)] #2283 I believe it was.
Let me explain the reasoning behind slugs. A high horsepower locomotive such as the GP40-2 CSX uses as master units are capable of producing far more power than can be transmitted to the rails via the four traction motors it has. By rebuilding some older units that otherwise would have been scrapped to slugs, the excess power from the master unit can be routed to the four additional traction motors of the slug unit. That excess power of the master is put to good use and you get a lot more tractive effort without having to have a second locomotive in the consist. There are different types of slugs--those for road use and those for yard use. The yard slugs are usually cut down to make it easier for yard crews to see over/around them. These yard slugs are used for traction only and usually have no dynamic braking equipment. The CSX road slugs retain their cabs and the consist can be controlled from either the slug or the GP40-2 master unit. Crews love operating from the road slugs as they are very quiet since they have no diesel prime mover. These units also have dynamic braking equipment which is a great asset in road use. To answer the question regarding prime movers, slug units have NO engine. All power comes from the master unit. In the case of the CSX road slugs, the doors that remain at the rear of the long hood are for access to an electric blower motor that is used for cooling the traction motors. Chris Toth
That heat and vibration was the small Traction Motor blower motor. now why was it running when the mother was off I dont know
YEE HAW I WAS WRONG AGAIN (I like that in way so then I can learn something) anyhow, there was another GP40-2 coupled nose to nose with it (forget the number) so maybe that's where it was coming from?? like this: <<8033 , 2283>> , <<6--- , 7014>> It just also might be a possiblity that only th C30-7(7014) was the only unit running other than the Unknown GP40-2 that supplied extra power to the slug hmmmm.

what Slug # (I'm thinking a GP35 slug) is mated with GP40-2 #6483??? 9 I saw it with a mate in town last night but I didn't get the number of the Slug.

Here's a picture of that unit (undated) from the CSX Photo Archives: Harold
well that pic of 2228 is out dated, I saw yellow ends and I think a blue cab, (regular paint job;Bright Future scheme) I could tell because the 2nd unit had no side doors and no roof blister(or whatever it's really called) so I assumed it was an Old GP35. THANKS HAROLD!
this is an add on to NSDASH9's post with the roster of Slugs: (the unit former types are from Examination of photos, correct me if wrong!) 2331 ---- ---- ---- ?/?? 2332 GP40 ---- ---- ?/?? 2333 GP40 ---- ---- ?/?? 2334 ---- ---- ---- ?/?? 2335 GP40 ---- ---- ?/?? 2336 GP40 ---- ---- ?/?? 2337 No Pic for this unit 2338 No pic for this unit 2339 GP40 ---- ---- ?/?? 2340 No pic for this unit 2341 No pic for this unit 2342 GP40 ---- ---- ?/?? 2343 GP40 ---- ---- ?/?? 2344 ---- ---- ---- ?/?? 2345 No Pic for this unit 2346 ---- ---- ---- ?/?? 2347 ---- ---- ---- ?/?? 2348 No Pic for this unit 2349 GP38 ---- ---- ?/?? 2350 GP-- ---- ---- ?/?? Please add to this if any thing or if anything is incorrect plese fix it. Most units maybe a GP40 with an exception to 2349 which seems to be a GP38 from that "box" between the only grills(immediately behind the cab) and the Dynamic Brake blister. I think these slugs have Dynamic Brakes because they still retain the DB fan and blister. They are also newly repainted so I assume they were recently rebuilt ?? once more, CORRECT ME IF I'M WRONG!! and ADD ON if you find the missing stuff!!
