Reverser box installed behind the main transmission, can then go just as fast in reverse..........

Last I heard, Western Star, owned by Freightliner, now builds their trucks in North Carolina. Peterbilt, a Paccar brand, is the other one I have seen Brandt use. Cummins seems to be the favorite engine used in either..........

Wizlish you are correct but just to add a point the exhaust valves were left open on Detroit 2-strokes while the liner ports were uncovered to aid in combustion chamber scavenging. When they closed the exhaust ports before the piston went past the ports going back up to TDC they then became supercharged

Brandt builds those railroad trucks, but I don't know what engine they use.

 


I indirectly asked this question last year in a different thread, and the answer is Brandt will convert whichever heavy duty truck the customer requests (with some restrictions of course)

 

 

Brandt is a custom truck builder,  They build to what the customer specs for their truck need ( Cost is always a factor in the final product).  Of Course they probably have 'their favorite builder'.. Since they are a Canadian Company, and most of the Brandt trucks seem to have the Canadian-built Western Star in their 'genes'

Here is a montage of their railroad-specific units @ https://images.search.yahoo.com/yhs/search;_ylt=AwrTceGoYN5V3dMAWE0nnIlQ;_ylu=X3oDMTByNWU4cGh1BGNvbG8DZ3ExBHBvcwMxBHZ0aWQDBHNlYwNzYw--?p=Brandt+Railroad+Trucks&fr=yhs-mozilla-003&hspart=mozilla&hsimp=yhs-003

Here is a link to a YouTube video of a Brant Truck moving a train of various MOW equipment @ https://www.youtube.com/watch?v=WvblEuLPmUQ

If curious, I recall seeing a Brandt Truck at work on an NS job down South with a string of cars.

Around here they seems to be a favorite for BNSF for various jobs.

The engines in these trucks could not turn backwards as the exhaust would leave the intake and it would suck air thru the muffler. The only engines i have ever seen do such a thing was a 2 stroke diesel such as the old Detroits. Sadly, they ran almost as good backwards as they did forwards.

 

But a Detroit is like an early 567 in that it uses a positive-displacement Roots blower for scavenge.  So the exhaust-valve timing is such that the Roots sucks air back out the scavenge ports to get enough charge air to keep the engine rotating?


 

 

Yes but the direction of rotation is not a determining factor of intake vs exhaust timing. That's part of the 2 strooke nature.

PACCAR originated as Pacific Car and Foundry, which also built railroad cars.

Kenworth and peterbuilt trucks are identical except for trim items . Both are built by Paccar. They have engines by Cummins, Caterpillar and Paccar branded DAF engines from the Netherlands. None of them are capable of direct reversal.

A internal combustion engine doesn't care which way it rotates as long as the fuel charge and combustion ignition (spark or pressure) are timed correctly.

One snowmobile manufacturer offers reverse on their products - when the reverse switch is tripped, the ignition electronics stop the engine and start it back up in the reverse rotation - when the switch is tripped again the engine will be stopped and restarted in the forward direction.  To do this the ignition electronics have 2 separate trigger mechanisms.  Maximum RPM in the reverse direction is limited by the ignition electronics, in the forward direction RPM are limited by the CVT transmission system.

Never too old to have a happy childhood!

The majority of truck makers don't make thier own engines, they buy them from a supplier like Cat, Cummins, International, Detroit Diesel, ect. You can spec a # of different engines in trucks. Mack, International, and Volvo are some of the makers that manufacture their own engines but you can spec other brands in their chassis. Same with the transmission and rears.

Without a doubt Kenworth!

Kenworth "prime movers" have the ability of rotate in reverse.  Peterbilt (spelled correctly) doesn't.

 

 

 

I'm not sure I understand this.  Wouldn't either one be a typical truck, with forward gears and reverse?

I fixed the spelling.  Maybe I was thinking of the classic truck driver's T-shirt slogan: "Old truckers never die, they just get a new ......"

 

 

 

ENGINES rotate in only one direction.  Through GEARS, a truck (or auto) can be set to go in reverse.  But, in a Kenworth, if something prohibits the engine from rotating forward, it has the ability to rotate in reverse!  That is what is unique about a Kenworth.

Since railroad locomotives don’t use direct drives as truck do, but electrical force, there is no need for a train prime mover to ever go in reverse.  But, in the case of trucks, instead of a Kenworth ripping the engine apart if it can’t rotate, it can try to rotate the opposite way.  I got that tidbit from an old trucker I once knew.

I suspect Brandt will build their 'body' on any truck chassis that the buyer specifies.

The claw is used for grabbing ties.

The ones I've seen are on a Western Star chassis and look like they could win a tug-of-war with a locomotive. Smile

Posted by Murphy Siding on Wednesday, August 26, 2015 8:02 AM

     I just saw a work train head by.  It had 4 open hoppers being pulled by a semi truck with train wheels attached.  It looked like an interesting set-up.  The truck had a claw* and a sleeper.  I couldn't see the bottom half of the train as the corn is now about 7 feet tall.  I presume trucks like this would have the ability to switch over to rubber wheel use easily.  Other than in a yard setting, it seems the claw would be of limited use mounted on a truck that has to drive on relatively level terrain?

*I don't know the proper name for the claw in a railroad setting.  My only experience with those has been at the carnival for a quarter.  I never have managed to pick up a stuffed animal or a railroad tie with one of those.
