Talk:Gas turbine locomotive

Power
The article states:

Even so, the turbine design used in these units is still the most powerful prime mover ever installed in a locomotive.

This is not true if you take into account electric locomotives. You'll find a few with more power at List of stock used by Swiss Federal Railways and I'm sure there are others (i.e. the swedish IORE). --Kabelleger 14:31, 3 March 2006 (UTC)

The prime mover is the diesel or turbine engine that powers the alternator. Electric locomotives rely on outside power instead of generating their own, so the fact is still correct. EASports 18:12, 3 March 2006 (UTC)

In that case I misunderstood the term "prime mover". Thanks for your explanation. --Kabelleger 19:43, 3 March 2006 (UTC)

This article seems to miss all information on the German gas turbine locomotives and power trucks (Class 210/219/602)


 * Feel free to add information on these engines if you have data on them. We will be more than interested in knowing bout them. Captain scarlet 22:33, 7 June 2006 (UTC)

Coal-firing
I have moved this text (which is speculative) from the main article. Robertson shows a diagram which confirms Sampson's information but also refers to problems with erosion of turbine blades by ash. This is strange because, with a conventional shell and tube heat exchanger, there would be no risk of ash entering the turbine circuit. This may simply be a mistake (due to confusion between the US and UK projects) or it may be that a different type of heat exchanger was used.

A possible explanation is that a "batch-type" heat exchanger was used in an effort to obtain higher efficiency. This would have consisted of two chambers, packed with fire brick, which would be used alternately. One would be heated by the combustion gases while the other was heating the air in the turbine circuit. Neither source identifies the type of heat exchanger used and further research is needed. Other contributors may have additional information. Biscuittin (talk) 11:32, 1 February 2008 (UTC)

Long Island RR Gas turbine cars?
I've found some info about (10?) gas turbine cars tested on the LIRR, but nowhere near enough to add into this article...can anyone help add these cars in? It would appear that the 1st car or 2 were Budd Pioneer III type carbodies, with 2 Garrett gas turbine engines and RDC style transmissions, and the later cars were Budd/Garrett (4 cars?) and (Budd/?) GE (4 cars?) dual mode Turbine-electric/electrics, but other than picture captions and blog/forum postings, I have no information (Read this as: I know they existed, but have ZERO usable references). Can anyone supply references? Wuhwuzdat (talk) 14:06, 16 March 2009 (UTC)

What replaced them?
After becoming uneconomical and being taken out of service, it would be useful to mention what took their place. Chris the speller (talk) 23:12, 9 February 2011 (UTC)
 * I don't know about the rest of the world, but in the US the GE U50 and U50C used recycled trucks from Union Pacific's turbines and the EMD DD35, DD35A and DDA40X were also designed to take their place. Union Pacific GTELs mentions this, but I don't think it belongs in this article. Hellbus (talk) 01:30, 10 February 2011 (UTC)

ALPS
They might make a comeback. "Advanced Locomotive Propulsion System", at the level of a research project, in the USA. murray_baker(at)ihug(dot)com(dot)au 124.187.75.22 (talk) 10:14, 20 October 2011 (UTC)
