You're in the mood for necroposting today, aren't you.Guilty 😞 Isn't the problem weight, not height? Non-dual-mode Chargers are 272,000 lbs, which is 21 tons heavier than an SW1001; a dual-mode version would be heavier still (this document has Siemens stating that a dual-mode Charger with third rail gear would weigh 291,500 lbs or 30¾ tons heavier than the SW1001; the document further states that such a weight increase limits speeds to 110 mph, at least for Amtrak's purposes). Thanks for the document/reference. I don't think weight would be a problem though. A hypothetical (huge emphasis on hypothetical) set consisting of say a single Dual-Mode Charger with 5 Mafersa coaches would weigh the same as a set of 6 M7 cars. I used the SW1001 as a reference point because it's the only LIRR locomotive that I've seen operate all over its territory (including Brooklyn) BTW. And what's the use of sending diesel-territory LIRR trains to Brooklyn, a destination that LIRR is already deprecating? And a highly short-sighted move on the LIRR's part in a time where politicians are calling for renewed service on the Rockaway Beach, Central, and Long Island City lines, but anyways, the main purpose of this would be flexibility. If a M7 going to Brooklyn craps out at Jamaica, you can have the Charger set that just completed its run from Patchogue across the platform replace it instead of having to rush to get another MU set out of the yard. The LIRR's current diesel fleet also won't be able to access Grand Central. |
