Posted by Jace on Thu Aug 2 11:30:47 2012, in response to Re: Amtrak's ACS-64, posted by Olog-hai on Tue Jul 31 14:34:56 2012. Is the track the same? More specifically, are the regulations governing track design and maintenance the same now as in the 1970's? Absolutely not - see my other comment for more. By the way, the EMD SDP40 spec shows a nominal weight of 396,000 pounds, +/- 4,000 pounds. That's 66,000 pounds nomimal up to a maximum of 66,667 pounds per axle. SP's SD45T-2's were 68,333 pounds while the MP SD-40's topped out at 69,000 pounds. Only very recently have railroads started to move above these weights: CSX is now going up to 72,000 pounds on their heavy (AH) GE's.Thanks for the correction on the E60's. |
