Blinkerdoors Posted March 9, 2009 Share #1 Posted March 9, 2009 Did NJ Transit purchase the multi-task engines(combination: electric and diesel). And if so, when will they go into service? Are they from Bombardier? (NJT):confused: Link to comment Share on other sites More sharing options...
kaback9 Posted March 9, 2009 Share #2 Posted March 9, 2009 Yes they are called ALP45DPM's or something like that, they are being built by Bombardier, they will look like ALP 46's except only have one cab end. Here are the technical specifications: http://www.br146.de/revisionen_daten/DualPower_10290_LOC_Sept08_en.pdf Link to comment Share on other sites More sharing options...
metsfan Posted March 10, 2009 Share #3 Posted March 10, 2009 Imagine if the put both power modes on at once...:eek: It looks a bit bulkier than the alp-46, a bit taller as well. Looks like the trucks are similar. One pantograph. I'm glad they have something on paper. I just really hope they are as reliable as the alp-46. - A Link to comment Share on other sites More sharing options...
R44 5278 Posted March 10, 2009 Share #4 Posted March 10, 2009 Only one pantograph for both directions? I doubt that having one end is even flexible in terms of switching trainsets. Link to comment Share on other sites More sharing options...
kaback9 Posted March 10, 2009 Share #5 Posted March 10, 2009 Thats allowable look at Amtrak, they run some keystone sets both directions with the same pantograph up. Its also fine for switching they switch diesels like the PL42AC from sets everyday. Link to comment Share on other sites More sharing options...
R44 5278 Posted March 10, 2009 Share #6 Posted March 10, 2009 For one thing, Amtrak doesn't care about what pantograph to use on the Keystone. The front generally reduces wear as it pushes against the wire, but can easily snag down the wire. The rear increases wear despite it sliding along the wire, but in many cases the pantograph gets destroyed without the wire snagged. The newer engineers tend to use the front pantograph more than the older engineers since the order to "reduce wear" was implemented on all Amtrak Electrics not that long back.

kaback9 Posted March 10, 2009 Share #7 Posted March 10, 2009 That has since been revoked there is no rule out there anymore saying that Amtrak engines must have a certain pan up for reducing wear if that was the case then we would still see front pans up on NER's and LD trains. The rule has been out of favor for a while... Link to comment Share on other sites More sharing options...
R44 5278 Posted March 10, 2009 Share #8 Posted March 10, 2009 What did you mean by NER and LD? Also SEPTA cares about reducing wear over snagging down sections of catenary, which justifies why they have the front pantograph order on all AEM7s and the ALP-44.

metsfan Posted March 11, 2009 Share #9 Posted March 11, 2009 It also allows locos with one bad panto to remain in service. Since there is diesel backup, no need for second panto in case of the single unit failing. - A Link to comment Share on other sites More sharing options...
R44 5278 Posted March 11, 2009 Share #10 Posted March 11, 2009 In that case, I wonder how would it do when it snags the wire in the North River tubes... Link to comment Share on other sites More sharing options...

North East Regional and Long Distance. Also the SEPTA units are in pretty sad shape...but thats an entire different story. They need some loving lets leave it at that.

kaback9 Posted March 11, 2009 Share #12 Posted March 11, 2009 In that case, I wonder how would it do when it snags the wire in the North River tubes... Then they would call in a unit from NYP to drag it in, or it would run under its own power...what else could they do assuming it has passengers on it, they will need to be moved ASAP.

R44 5278 Posted March 11, 2009 Share #13 Posted March 11, 2009 no diesel in North River tunnels Link to comment Share on other sites More sharing options...
kaback9 Posted March 11, 2009 Share #14 Posted March 11, 2009 Depending on where it is in the tunnel would make the call, if they were close to NYP or Bergen they would turn it on to get it out(meaning it was near one of the portals) if not like I said they would bring something in to get it... They don't just leave trains full of passengers in tunnels that would be a media circus. Link to comment Share on other sites More sharing options...
metsfan Posted March 11, 2009 Share #15 Posted March 11, 2009 If it was a wire problem, they would probably turn one motor on for HEP, and one for traction, this way reducing any emissions while keeping passengers comfy & safe. I have seen a gennie sitting at the edge of the covered area at nyp fully on in idle (not low idle). If it's an emergency, theeasiest fix is obviously the diesel engines, simply go whichever way is fastest to exit. There is one fan plant you can see from HBLR that is equidistant from the center of the river and the tunnel entrance in NJ. - A Link to comment Share on other sites More sharing options...
kaback9 Posted March 11, 2009 Share #16 Posted March 11, 2009 Exactly, no diesel in the tunnels is a myth it can and has been done, its not allowed for daily operations but in extreme emergency situations or crisis it can be used, that and NY has strict emission laws.

Jamaica Express Posted March 11, 2009 Share #17 Posted March 11, 2009 I just hope these diesels don't turn out to be like the LIRR ones, resulting in extremely limited direct service for diesel territory.Other than that I am excited to see how this turns out. Especially for :rvl: which is screaming for direct service into NYP. Link to comment Share on other sites More sharing options...

You and me both, I'm hoping these things go through some major testing before put in revenue service, at least if they do fail NJT could convert half to Electric engines and half to diesel Link to comment Share on other sites More sharing options...

R44 5278 Posted March 12, 2009 Share #20 Posted March 12, 2009 I hope that these units would result to be fuel efficient and has more power running with electricity than diesel like the DM30AC. Reach for 125mph on the Lackawanna Cutoff! Link to comment Share on other sites More sharing options...
Fan Railer Posted March 12, 2009 Share #21 Posted March 12, 2009 well, check the wikipedia article on the ALP-45DP. I updated the page with the current specs from the document and also calculated fuel efficiency. Link to comment Share on other sites More sharing options...
metsfan Posted March 13, 2009 Share #22 Posted March 13, 2009 The great thing about these new locos, is they will likely be able to have one of the 2 diesel engines running so no need for immediate rescue. Also, having 2 smaller engines means you can upgrade them without tearing the whole loco apart. This is good, because the switch to bio-diesel will likely happen on their watch. Also, you have total flexibility for yard switching, you could put then at any of the yards. This will likely be what happens to a few of them. - A Link to comment Share on other sites More sharing options...
kaback9 Posted March 13, 2009 Share #23 Posted March 13, 2009 Uh? They are possibly the worst unit you could use for yard switching...that is going to remain a role of the geeps, with their cab configuration the way it is(being able to look both in front and behind you), what your saying is equivalent to using a PL42 as a switcher. Can they do it yes, but these things are being built for revenue service. The geeps serve both revenue and non revenue for NJT. Also they would not have bought the MP20's if they thought they would use these for yard work. Link to comment Share on other sites More sharing options...

All true, just saying that they have an advantage if it ever came to that, not that it would be ideal, or that they would. :cool: Can't really dispatch a work diesel into NYP to pluck a disabled train out, can work under yard catenary with empty tank. Just saying that they will have those options if they needed it. - A Link to comment Share on other sites More sharing options...
kaback9 Posted March 13, 2009 Share #25 Posted March 13, 2009 Yeah, they could do that, but by the same fortune I think if something gets stuck in the tunnels that is primarily Amtrak's job to get it out, they usually keep power at NYP just for this but I could see them doing something like you mention especially if they have a really bad day where something gets stuck on the Empire connection due to an equipment shortage and has a P42 or a stalled train talk about what a bad day that would be.
