BlastOButter42 Posted August 4, 2009 Share #27 Posted August 4, 2009 From having been in the cab on the LIRR when I was little I used to see the M3s get up past 80 pretty regularly. Not sure exactly where, but before Jamaica on the way in. Link to comment Share on other sites More sharing options...
Matt91 Posted August 6, 2009 Share #28 Posted August 6, 2009 Some of the diesels really fly between Bellerose and Mineola. Not just there. My 4:49 express (Dual ModE diesel/electric) from Penn must do about 75 from Penn to Jamaica and flies from Jay to Hicksville. Also does good b/t Hix and Syosset. Pretty much after that the whole PJ branch has curves and the train slows to like 45 or 55 especially east of Greenlawn Link to comment Share on other sites More sharing options...
metsfan Posted August 7, 2009 Share #29 Posted August 7, 2009 LIRR trackage standards can support 85 mph. - A Link to comment Share on other sites More sharing options...
Amtrak7 Posted August 7, 2009 Share #30 Posted August 7, 2009 Well: http://www.richegreen.com/NYCTrackMapV3.pdf MAS for electric is 80, diesel is 65. Note that speed also depends on signal indication. Unlike NYCT, where approach just means prepare to stop at next signal, LIRR has multiple signal progressions and specific speed restrictions for certain signal types. Also remember that there is also unsignalized territory where written or dictated orders control speed. Engineers must memorize location of each speed restriction and braking point. Unlike NYCT, where the train can slow quickly, LIRR is heavy rail. Link to comment Share on other sites More sharing options...
traildriver Posted August 8, 2009 Share #31 Posted August 8, 2009 The R44s had a speed test on LIRR tracks, going past 70 mph.The average maximum speed is kept at 55mph due to the space between stations, curved tunnels and intense interlining. The speed is higher on the LIRR due to longer distances set and in general, most tracks are straight. According to Gene Sansone's book on the history of NYC subway cars, on 31 JAN 1972 a special test was run of new R44 cars on the LIRR mainline on a 5.9 mile stretch of track between Jamaica and Woodside where the cars achieved a record of 87.75 MPH!

That is PRR revamped "bread & butter" trackage, everything to the west, you don't want to go that fast. The tracks have a lot of medium and low speed interlocking & if you cross them even not switching too fast you're going to have a bad day. Happens all the time at jamaica. - A Link to comment Share on other sites More sharing options...
Andrew Posted August 21, 2009 Share #33 Posted August 21, 2009 Metro North trains reach 90MPH at the Mamaroneck Station.I have seen Acelas reach 100MPH there. Link to comment Share on other sites More sharing options...
Jayjay1213 Posted August 21, 2009 Share #34 Posted August 21, 2009 Metro North trains reach 90MPH at the Mamaroneck Station.I have seen Acelas reach 100MPH there. I hope you didn't see an Acela doing 100mph there, regardless of wether its MN or Amtrak, speed for passenger trains thru Mamaroneck is 90 mph Top speed for passenger trains on LIRR is 80, freight 45. On MN passenger trains is 90, and 50 for freight. Link to comment Share on other sites More sharing options...
