Yup, and an unbelievably badass mayor DROVE A LOCOMOTIVE 1000 FEET FROM THE TRAIN TRACKS DOWN THE ****ING ASPHALT ROAD to the town square to use it as a makeshift generator to provide emergency power.

Ever want to see a locomotive driving under its own power directly on asphalt with no tracks? Here you go:

He took care of a problem the best way he could, a heck of a lot more than most Politian's do

I lived through this in western Quebec near Ottawa. 10 days without power sharing a generator between neighbors to keep our freezers frozen and the furnace running enough to stray warm. I totally missed this innovative lady getting done with what was available. Mt French is rusty but I think I understood 550 kilowatts available from the locomotive. Enough for a few light bulbs.
Better than my French, which is non-existent. I read from another article that the rated power of the locomotive was 2000 hp (about 1.5 megawatts) which would probably light up most of the town. The problem with that is the engine would be spinning too fast and the AC frequency would be much too high. So they had to slow the engine down to produce the 60 Hz that we all know and love to prevent things like the compressor in your fridge from self destructing. At the lower RPM the locomotive was only good for 350 kilowatts, which is still quite a lot of power.Quote:

Trying to think through this process fills my head with questions. Did the cranes that lifted it off the tracks have to follow along so they could steer it? Was the road flat enough to keep most of the wheels on the ground during the trip? Trains to not have much travel in their suspension systems. Even after getting the locomotive in place, it is not just a matter of plugging it into the grid. In addition to the getting the cycles right, the voltage has to match what the transformers are expecting. I don't know enough about locomotives to know the voltage they use. Do they vary cycles or voltage to control speed/power in normal operation? They have to disconnect their little section of grid from the main grid to keep from killing the workers repairing the damaged sections.
They need to have one of these for next time. I bet this would be less expensive than all of the work and repairs needed to the road and the locomotive. :D

I cannot make this thumbnail go away.
After this storm many critical buildings actually have permanent backup generation. Fed by natural gas where possible.Quote:
