The 2-71 units seen here are in Pocotello, Idaho and are coming from Union Pacific reefer cars. Those were the first 'slow speed' gensets I investigated. I used to sell material to the UP rebuild shop and know several guys over there. They tell me to 'forget about it'. These units were installed at the factory, plumbed to run off BIG fuel tanks, cranked and forgotten until they started to break down. Most are being replaced by Yanmars.
A 'neighbor' has one of the 2-71s he got from a train wreck several years ago....he kept putting me off when I ask to hear it run. When he finally torched it off *I* nearly ran. NO way to have one in a residential neighborhood that I can see!
Bye the way--- I run a Listeroid about 16 hours a day as a sole source of power. You can expect to pay about $.35/Kw hour if you run red diesel .....and work on the engine will take up *some* time.
Grid power is a BARGAIN!!!
