A Lempor exhaust system was tried on 3985. it was an abject failure. After a couple of trips where she did a rolling tribute to Vesuvius erupting, the Lempor was ripped out and unceremoniously tossed in the scrap dumpster behind the Cheyenne shops. Maybe Otto Jablemann and the engineering department at ALCo got it right, after all.
I am told that Steve Lee gave a cogent and concise assessment of the Lempor system. Unfortunately the adjectives and nouns he used preclude it from being quoted on this site.
