QUOTE: Originally posted by CSSHEGEWISCH Turbocharging and supercharging can boost horsepower ratings pretty high, but the maintenance requriements also go up as the ratings get higher. In a similar vein, I am quite amused by the various ads for automobiles boasting of their horsepower rating without mentioning that the advertised horsepower is achieved only at close to maximum RPM's.
QUOTE: Originally posted by Sterling1 QUOTE: Originally posted by oltmannd For RR service, the traction HP is as follows: 16-645E - 2000 HP 16-645E3 - 3000 HP (although UPs Centenials were rated at 3300HP) 20-645E3 - 3600 HP 16-645F3 - 3600 HP You can squeeze more HP out of the turbocharged engines, to a point, by increasing the fuel and/or engine RPM, but that will cost you in reliability. The EMD 16-710G3 started life rated at 3800 HP. This was later bumped up to 4000 and now to 4300 HP. A similarly rated 20-710G3 would give you roughly 5500 HP. I know that UPs Centenials may have had supercharged 16-645E3 engines. Matt

Are there any differences because I noticed the numbers scheme didn't particularly go inorder. Also what was the deal with EMD SD45X 5740? Anyting different in this locomotive from SD45? Matt When we started the WC we got a group of SD-45s from the BN. The numbers were a jumble of numbers from 6400s which were the ex Frisco engines, the 6500s that were single electrical cabinet BN units and some 6600s which were a mix of ex Frisco, and GN. As time went on we were continually renumbering locomotives that were run through some kind of program. The locomotives numbered in the low 6500s were given Q-Tron micro processors, mainly because they had one main high voltage cabinet. I think the Q-Tron numbers were 6501- 6533. In the last few years of the WC we were also rebuilding the 20 cyl engines, we then renumbered them into the 7500s to reflect the work. The 6400s and the 6600s were a troublesome group and it was decided to rewire these engines and apply the EM 2000 micro. We went ahead and renumbered all of them into the 6495s until we also rebuilt the prime movers and renumbered them again into the 7495s. We bought a group of engines from the ATSF and began numbering them 6578-6598. a second group from the ATSF began at 6599-6624 I think. We also bought a few one off engines from Helm leasing, If I remember right we started numbering those right after the ex santa Fe engines. We also bought a few SDF-45s from the Santa Fe and stated numbering those in the 6650s. Randy

QUOTE: Originally posted by Sterling1 I was thinking: Norfolk Southern(NS) has some units which have head and ditch lights on both ends. Which locos are these; I am looking for road numbers and types (GE, EMD) and which models. Thanks in Advance Matt
QUOTE: Originally posted by arbfbe Technologically, it is possible. That is just what happens when a train with remotes backs up, isn't it? Generally, it would be a bad idea and not allowed by any sort of railroad rules I am aware of. Get off the caffine, Kid..
