The charger is also much lower than Gennies, 12 foot something vs 14'6".
The ACS-64 seemed bigger when I stood next to it, but that's just me. The ACS and Chargers are the same height I think.I thought it looked "sleeker" than the GE P42. Turns out, it's almost 2 feet shorter!
Would this be a long-term replacement for the P42s?
Thanks for finding the info. Wow.
HUZZAH!!!!The test plan for 125 mph testing on the North East Corridor is being prepared and will be submitted to FRA by MARC, with IDOT/JPE will send letter of concurrence.
The NGEC report says nothing about anyone funding to build a dual mode yet. All that it says is the specification is being completed. We are a few years away from anyone actually building one, and it is not a given that Siemens will necessarily get the order from that procurement process. They might, but it is yet to be seen.Two very important points in the report/
1 Plans for 125 MPH tests by MARC on the NEC. Between Wash - Baltimore or north of Trenton which can provide track rated higher speed for the FRA requirement of testing at speeds above final rated speeds. Can we assume that will be after testing at the TTC ( Pueblo ) ?
2. The building of a 3rd rail dual mode loco. That unit would only be needed on the Empire corridor Albany - NYP. So Amtrak must be planning to replace its DMs sometime in the near future once the 3rd rail Charger proves itself ? As well 125 rated speeds on those portions of the Empire corridor that Amtrak may increase speeds to. That certainly does not preclude some agency from installing a third rail section in say a terminal station but that seems highly unlikely..
3. One has to wonder if Siemens also plans a dual mode CAT loco very similar to Chargers and ACS-64s ? Maybe a future replacement to the NJT ALP-45DMs ?
The Dual Mode (DC 3rd Rail) Locomotive specification document has been available in draft form in a sequential series of revisions for years. We have discussed the specification and reports before. First, this would be a NYS DOT purchase as they are the lead agency on the Dual Mode specification. There are statements buried in the lengthy activities reports that NYS DOT plans to start the RFP process after the Dual Mode specification is finalized, but that could be years. The state has to budget for the locomotive order first.2. The building of a 3rd rail dual mode loco. That unit would only be needed on the Empire corridor Albany - NYP.

The pending final Dual Mode DC 3rd Rail locomotive spec and subsequent RFP has been discussed in this thread before; see page 2 for example. It is generally off-topic for the Siemens Charger contract and delivery. if the subject is going to keep coming up (lather, rinse, repeat) and it will once the final spec and requirements are posted, we should have a separate Dual Mode DC 3rd Rail thread on it. With links to the AASHTO NGEC documents page(s).I am disappointed that they're making a DC 3rd rail dual mode spec, and are not making an AC overhead dual mode spec. DC 3rd rail dual mode is primarily of use to Metro North, and nobody else. Amtrak could use either, but would have more use for an AC overhead design.
Thoughtless.

These would not be 125 mph locomotives. The specification calls for 110 mph max speeds in diesel mode, 80 mph in 3rd rail mode. The earlier drafts called for 125 mph max speeds, but the committee changed the requirement to 110 mph after feedback from the manufacturers on weight and car length issues for the 3rd rail DC gear and energy storage system.
Finally, the Dual Mode (DC 3rd rail) locomotive order would be a new bid, so EMD and possibly Motive Power would be submitting bids. Siemens presumably has the edge in getting the contract, but since this is NY State, politics could be the deciding factor in who gets the contract (whenever that happens).
From the part you quoted: "feedback from the manufacturers on weight and car length issues for the 3rd rail DC gear and energy storage system."Why not 125 MPH?
More detailed answers to your question can be found in the Dual Mode specification and requirement related documents on this NGEC Documents/Specifications page. Look for the discussion points for 125 vs 110 mph document under the Dual Mode requirements. Further info about the technical issues raised by Siemens for the Dual Mode loco is in the activities report available elsewhere on the NGEC pages.Why not 125 MPH?These would not be 125 mph locomotives.

Oh, I see. So weight is one of the main problems.From the part you quoted: "feedback from the manufacturers on weight and car length issues for the 3rd rail DC gear and energy storage system."Why not 125 MPH?
Weight is one of the biggest considerations in the design of any vehicle, as having too much on the wheels can lead to restrictions of where that vehicle can be used. A good example is the Airbus A380-800 design process as this aircraft was forced to cut almost 30% of its original weight once the configuration was set. If the weight was not cut, it would have cracked the taxiways and runways wherever it went.Oh, I see. So weight is one of the main problems.From the part you quoted: "feedback from the manufacturers on weight and car length issues for the 3rd rail DC gear and energy storage system."Why not 125 MPH?
Plus, of course, that they don't NEED to run 125 mph on the short run out of NYP. There's what one to three miles of third rail going out of Penn Station.Oh, I see. So weight is one of the main problems.From the part you quoted: "feedback from the manufacturers on weight and car length issues for the 3rd rail DC gear and energy storage system."Why not 125 MPH?
