Thanks again! The TE-1 in the photo looks as if it is lovingly cared for: somewhere in Russia there is a railroad museum that puts most of ours to shame!
As for how they got a modified 539 up to 1200 hp... The entry in "Jane's World Railways" doesn't give any details (other than that the uprated engine has a speed of 750rpm instead of 740).
(I wasn't thinking of Alco's hypothetical 1200hp engine as an alternative to the 8-251 in the 1960s: more something that could have been built in 1950 to produce a switcher competing with EMD's SW-7/SW-9 and BLH's S-12: I think Kirkland's Alco book says that some thought was given to uprating the 539, but that resources for development were limited and it was felt that perfecting the 244 was higher priority.)
