Given that this is essentially a two part vehicle, I'd like to introduce you to the SBB Re10/10 double traction electric locomotive of 11,597 hp at up to 140 km/hr.
@@DerekWalsh-l4i Why use a weak, difficult to maintain, diesel when you could have a much more powerful electric locomotive at double the power. Those four fixed axle bogeys is a big no no for me anyway.
Centennial series locomotives built ca. 1969 to commemorate the 100th anniversary of the driving of the golden spike. When I was in the air force, I did some temporary duty at Nellis AFB near Las Vegas around 1981 or so. There was a long line of these Centennial locomotives in storage on a siding just outside of the city. Very impressive locos.
I've ridden a UP excursion train from Denver to Cheyenne and return that was pulled by one of these locomotives, known as "Centennials" by Union Pacific. I believe UP has - or had - a total of 11 of these. 6,600 HP. I believe all of them are now retired from regular service.
Впервые увидел рисунок этого локомотива в одной книге по тепловозам, в библиотеке ДИИТа, в 1985 году. Его параметры меня поразили,особенно "жесткая" четырёхосная тележка.

@@nated1327 might see it again if they can run it west of the iowa interstate. it seems like most things go to bureau junction, where the line splits to peoria.
I've never really understood the point of why these were ever constructed. Why did they not just build some regular cabless B units and couple them to the primary units? Why make something even more unwieldy and less maneuverable?
At the time these were built, 1969-1971, EMD was experimenting with very powerful locomotives. The X in the designation stands for experimental. They were reliable and performed extremely well, but they were expensive to maintain so EMD did exactly as you suggested, lashed together smaller units and DPUs. It was really the peak of the experimentation with very powerful units, much like the turbine locomotives that UP had earlier and which were used (mostly) on the very flat portions of the system, though they did well in the mountains as well, such as the Feather River route (rarely seen there).
This monster is almost 4x more powerful than the Dinky little 105 tonne 1,750hp Ex British Rail Class 37's I used to drive in UK before I retired.... I wonder what the fuel consumption is in gallons per mile is for this monster at full throttle... A Class 37 would be doing less than 1 gallon per mile... with the regulator wide open hauling a heavy train.... No such thing as dynamic brakes for holding back heavy trains when going downhill though....
She's a big girl for certain. It appears that this unit actually has 2 diesel engines in 2 separate compartments. This locomotive is about the length of the Northern Type steam locomotive which is about 240,000 lbs heavier than this Union Pacific unit and with the power of steam, has a whopping 20,000 HP vs this diesel at only 6000 HP!!!
