These locomotives don’t get much attention as more common A units.
All discussions and pictures relating to slugs and B-units are welcome.

I love the way GP60s look, either A or B units.

Here's an SD45B
>>
>>1731634
They do have very clean lines. In fact I think all B units do, there's no cab to break the outline.
It's a similar thing to CSX and NS' road slug conversions, there's very few grilles on the side. They look neater than the mother units

More tractive effort, which helps prevent trains stalling.
In addition, they help to reduce fuel use as they don’t have a prime mover idling and contributing nothing on easier sections.

It’s why several shortlines use them (pic related Pacific & Western) as their slower speeds require less hp, but they have high tractive effort needs. Ideal conditions for slug usage.

>>1731841
Until you lose the leader/supplier. Then you're out 2.
>>
>>1731846
Good point, especially with a road slug and single mother unit. However, if you have the slug sandwiched between two mothers then it can still contribute TE, the train will just be slower. Though you’ll still be down 1 unit worth of hp either way and have the deadweight of the failed unit to lug around until it can be detached.

Most of the jobs that get assigned road slugs don’t have speed as their top priority. It’s not like a manifest would have slugs attached as road power.

SNCF Class C 61000 with TC 61000 slugs in the 70s. All have been withdrawn. Twelve slugs were built, and only one still exist today (sadly not working).

The UK had something similar with the BR class 13. They were a permanently coupled master/slave unit made from two class 08 diesels.

They were used in Tinsley yard to push wagons over the hump without grounding.
>>
>>1731942
Was that a slug or a B unit? Looks awesome
>>
>>1731943
A and B unit. Both still had their 350hp engines, so neither was a slug.
Along with one having the cab and controls removed, they had extra weights added to assist adhesion.

Quick question, train autists. I saw a car that looked like this today, I was wondering what it's purpose was. It was flat and had a central divider running lengthwise along the platfoem. There were oval cutouts in the divider.
>>
>>1732416
It is a center beam flat car, it's used for moving lumber and wallboard
>>
>>1732418
Thank you
>>
>>1732351
yeah but I doubt it will take long before they are modified and relegated to B unit status, permanently coupled to a diesel so it can be charged on the go.
>>
>>1732751
>permanently coupled to a diesel so it can be charged on the go
Doesn't make sense. You're just putting more hours on the prime mover to charge it, which results in higher overall emissions and energy wasted through converting the energy in fuel to electricity.

Robot-5 was an old MLW (Alco) unit. I remember seeing it many times back in the day when the most common CP Rail robots were made from boxcars.

When you say "old baggage cars" do you mean the express reefers?

I like B-units, C-liners especially.

SNCF class BB 64700 with TBB 64800 slug, used for yard shunting.
Basically an upgraded SNCF class BB 63500 (new cab with new controls, AC alternator instead of DC generator, received later a new engine) coupled with a heavily modified BB 63000.
Some are fitted with radio-control.
Fun fact : They have been designed this way so they could fit without uncoupling on the workshop's 24 meter (78.74 feet) turntable where I work.

It's an automatic couping for switching operations.
Since buffer-and-chain couplers are rather work-intensive to couple correctly, switchers are often equipped with these to just grab the hook on the railcar to drag it about. As the brakelines etc. remain unattached, this is for switching only.
Here's another image of a german one.

Theyre nice on the yard jobs and locals when you dont necessarily need another motor but you need a little more power. Especially for the yard jobs. We just had one of our GP35s rebuilt with the medha system and if you laced a slug to it, that pair would easily switch the longest track we had on our line

>>1732308
I work for a shortline in the midwest
>>
>>1733957
Why shortline? Why not class one?

Actually anons, wouldn’t re-motoring the older B-B diesels with AC motors work better than having a slug?

You can get ~100k-lbf or more out of 4 AC motors. There’d be fewer units to maintain and the efficiency would improve as the train:loco weight ratio would increase.

I understand expense is probably the main reason for this not happening already. Are there any other reasons why?

better working schedule, pay usually isn't too bad

Working for a class 1 sucks ass

>>1734067
It would mean a locomotive rebuild. In addition to the traction motors you'd need to swap the generator for an alternator and replace the electrical system. But a rebuilt 4-axle locomotive (DC or AC) is more practical than converting it to a slug for most railroads.

Shortlines are great. This is the second one i worked for. Usually management is a lot more relaxed as long as you get your work done. We still run on 40mph CTC territory. Were basically a class 1 branch line with how much we move and how our operations are.
>>
>>1734315
Depends on your job. When you start youll be at the bottom of the board so expect nights, weekends, holidays, etc. The good thing about shortlines is youll move up in seniorty quicker. When i hired out i was spot 36 on the board 4 years ago. Now im spot 12. The last railroad i was on i was spot 18 when i hired and i was spot 10 when i left there

But according to Trains, they were moved temporarily
