Rayman4449 Posted May 9, 2014 Share Posted May 9, 2014 There is a group that has been established to build a full scale replica of the PRR T1 Duplex drive engine. http://prrt1steamlocomotivetrust.org/ Quote Link to comment Share on other sites More sharing options...
Jim Miller Posted May 9, 2014 Share Posted May 9, 2014 Boy, there is one for MTH to do in 1 gauge..................Jim Quote Link to comment Share on other sites More sharing options...
Rayman4449 Posted May 9, 2014 Author Share Posted May 9, 2014 I agree with you. MTH is the only chance to see one being made that's affordable. Quote Link to comment Share on other sites More sharing options...
Jim Miller Posted May 9, 2014 Share Posted May 9, 2014 I hear you have a lot of influence at MTH, is that correct.................Jim..................... Quote Link to comment Share on other sites More sharing options...
Rayman4449 Posted May 9, 2014 Author Share Posted May 9, 2014 Haha well I do periodically remind them of models I'd like to see. Ultimately of course any next engines I'm sure will be based on sales numbers their O gauge line. Quote Link to comment Share on other sites More sharing options...
enginear joe Posted May 10, 2014 Share Posted May 10, 2014 I have one in O scale 3 rail (20-3043) just sitting because I run 2 rail. I liked the look of her so I may add a three rail line to run engines like her. Pennsy had some awesome looking steam engines. The big tenders add to the overall look too. Too bad MTH didn't go deeper into G gauge for us. Quote Link to comment Share on other sites More sharing options...
Rayman4449 Posted May 10, 2014 Author Share Posted May 10, 2014 I hope MTH makes one at some point, I would bet it would be awhile before they got around to that particular prototype. As it is Accucraft seems to be struggling to find a next model to bring to production that is viable (based on pre-orders) and I don't think we have heard a word from USA Trains on their next steam engine since the Big Boy which was announced in 2005. (I think I heard a rumor about an 844 from USA Trains but other than that mention that's all I think) All the mfgs appear to be proceeding very carefully. When you say didn't go deeper, do you mean didn't produce more during their initial push into G scale? (ie. beyond the Hudson, Challenger, Big Boy, GS-4, GS-2 and Triplex) I'm asking cause this is spoken in a way that could be construed by the uninformed reader that they aren't ever making new product designs and are out of G scale neither of which is true. MTH did in fact produce a new 2013 catalog which proved they aren't out of the One Gauge market and we just heard Mike Wolf say the next scale to get the GE ES44AC Evolution Series is One Gauge (my guess will show up in the 2014 catalog). MTH is also on record saying they already have another steam locomotive sized up to 1:32 and is just a matter of bringing it to production. They said it would be a smaller one but I have to think the next sizable engine in steam would most likely be a N&W J class. Quote Link to comment Share on other sites More sharing options...
Chuck Posted May 11, 2014 Share Posted May 11, 2014 You know I've been kind of following the T1 Trust for a few years on another forum and I don't know what to think about them. They do seem sincere but when hard cold questions are asked they sort of side-step answering them. The biggest question is where will they get a Duplex frame? Those cast frames were some of the largest pieces ever made in the world at General Steel Castings in Granite City, IL. but that company is long gone and so is the art of large sand castings. Suppose it could be made up of weldments but would it hold up? Cast steel is a heck of a lot tougher than a weldment BUT the engines that EMD makes theses days are a weldment and not cast. Next question is where are they going to operate it? The PRR had severe restrictions on where the Duplex's could run and it seems to me they were limited to between Chicago and Ohio because of curve and clearance issues so that negates the whole East Coast. Another question is where to make those main & side rods out of the exotic materials that were used? Lightweight and strong so as not to throw off the balancing which is also a lost art. Then come those rotary poppet valves and where to pickup where the PRR left off on the development of them? I do wish them the best of luck but I'd think they'd be better off finishing K4 1361...the one that got botched up when it was attempted to restore it.

Rayman4449 Posted May 11, 2014 Author Share Posted May 11, 2014 I do hope someone takes up the effort to save the K4, that project did turn into a disaster. A K4 would be a really iconic engine to have back under steam. Quote Link to comment Share on other sites More sharing options...
du-bousquetaire Posted March 4, 2015 Share Posted March 4, 2015 Just to give you an idea of what it would be like this is my Accucraft one in steam with prototype prr diagram cars in tow. This engine really needs wide radius though, just because you are running at passenger train speeds, not freight ones... It is very easy to drive and has a fantastic boiler. Now it will even have some PRR position light signals on its way. I scratch built one last year. it can indicate 9 positions manually. MTH and live steam work well together, just the problem of insulating steamers, I am thinking about battery operation with DCS as Garry Raimond described to overcome this. Enjoy!

Rayman4449 Posted March 7, 2016 Author Share Posted March 7, 2016 Such an excellent model you have there Simon, I would love to have one!

Screwy Nick Posted August 11, 2016 Share Posted August 11, 2016 Latest issue of Popular Mechanics has an article about how they are making the same steel that the original was made of, seems to be a discontinued formula. Quote Link to comment Share on other sites More sharing options...
Jerry B44 Posted August 11, 2016 Share Posted August 11, 2016 I just can't imagine this happening. Soooooo many parts. Quote Link to comment Share on other sites More sharing options...
Screwy Nick Posted August 11, 2016 Share Posted August 11, 2016 I wonder which has more parts, Diesel or Steam locomotive. Todays technology and now that the steel formula is being produced seems the only thing needed is time and money. Many years left before it will be running, but what a site to see it will be.

enginear joe Posted September 24, 2016 Share Posted September 24, 2016 Wow, that is cool. I wish them well. I just read an article in MRC mag about how they rebuilt one from an accident with a 4-8-4 mountain's chassis. The story says that the new configuration probably would not do the 110 MPH smoothly as the original did. They must have really been at the cutting edge near the end of steam. It makes sense, learning why these old steam engines were so admired by the older guys. Quote Link to comment Share on other sites More sharing options...
Rayman4449 Posted September 24, 2016 Author Share Posted September 24, 2016 I wish them well also and hope they get enough donations to make this become a reality (I've donated). This has to be the most ambitious steam project ever undertaken (post the steam era) to build an engine like this, of this size from scratch.
