Posted by AEM-7AC #901 on Sat Jul 5 17:43:34 2008, in response to Re: NJT Board considering large capital expenditure on new rolling stock, including DMs & EMUs, July 9th, posted by RonInBayside on Sat Jul 5 16:11:44 2008. You want to avoid a Ronkonkoma type situation (is that the appropriate comparison?)That's the most extreme situation due to the scarce diesel service, but it's the perfect example of what I'm talking about. Due to the lack of frequent and direct service to Penn Station, riders flock to Ronkonkoma crowding the large lots and overburdened Long Island Expressway to get there instead of using stations closer to home. The problem is exacerbated by the LIRR's electrification system which means that any extension to the next stop, Medford, will require at least two to three substations alone. In contrast, with an overhead catenary system, two or three substations would have been sufficient to electrify as far as Greenport. While many may say that the service out east has no need for electrification, the LIRR gets the benefit of reducing its need for what may become an decreasing diesel fleet. So instead of buying expensive diesel locomotives that will see little use with extended electrification, the LIRR can simply order more MUs (read: large M-8 order) or buy an off the shelf electric locomotive (read: ALP-46A) with specifications for 750vdc third rail, 11kV@25hz & 25kV@60hz overhead catenary. Mind you, this is all in the long-term 15-25 year horizon at minimum. This is definitely not in the short or medium term range in terms of planning or any implementation. |
