A Mystery Locomotive used as a DPU pushing up the end of a very long train! 

It's a specialized unit called a Self-Powered-Slot (SPS). It is used in a consist called a Slot Machine, with specialized gondolas and an excavator that can travel the length of the consist while performing MOW work over the side, along the rail line.

Self propelled slot machine. I have a video of two of them on the tracks When i saw the first one on the tracks it took me by surprise. Cool capture on that one.

Awesome video RTS. Loved the train mix and different locations. The Triple Crown Express looked to be longer today. I’m amazed that only one locomotive pulls that consist into Detroit. Thank you also for the great comments.

Odd Catch on the End of the Train. 🤔👍🙏

Here's what you find if you search that ?? DPU. Grex 6008 road number Owner: Georgetown Rail Equipment Company Model: UNKNOWN UNKNOWN Built As: Builder Info (Unavailable ) It appears to have only 4 axles

busy day on the Wabash! Great video and I have to admit "Danes pass" as it used to be called was my favorite location to watch trains. Tall Sycamore used to let us throw a tent up down by the east end of the siding and we'd camp all night and day there. Those were the days!

Excellent video my friends awesome like and Greeting😊

That was awesome seeing the road railer, especially since I thought they had been discontinued!!

The GERX unit on the end is a MoW motor, not being powered as DPU. In tow for somewhere. It’s used for Slot car MoW equipment. The motor was probably a rebuilt EMD like a MP15 or GP38.

That first train was an improperly built train! The mid train DPU’s had flammable hazmat cars right against engines with no cover.

It's not a DPU. It's just being towed.

Nice catch never seen it before

GREX 6008 is a modified GP38M. MOW equipment.

Plenty of fast moving trains today with a good variet of equipments and closing with a road railer really moving along. Nice to see the BNSF power and it sure was an Automax day. GREX Georgetown RR probably has a few of these built on the frame of a GP38 just like Loram and Speno have done. The easy way to remember the Georgetown equipment are the 15 cars with a conveyor belt climbing in between every one of them

Enjoyed this video, didn't know if I would see the triple crown again! It was a long train that day. 😊❤👍

GREX unit on the end.

Pretty cool from Plymouth Indiana

I love them articulated autoracks

The GREX 6008 was built as SD60 #6018 for the SOO.

New one to me too!

Awesome share

That GREX unit was most likely D I T

I've seen a lot of trains but never a locomotive in between cars

Why do you use 2 cameras to take of the train. Cause it's hard to count the trains

Nice ending with the Triple crown. I heard they are done, any news about it, anyone?

That Triple Crown train, how many trailers does it normally contain?

Is GREX 6008 on DPU!

It's GREX Unit

Certainly not a mystery locomotive and NOT in any way a DPU unit on its very best day. Could not recieve a signal if it wanted to.

Nice footage, I have only seen those on MOW equipment trains usually!🛤🚂
