Hi,

Yes it was a lot of work. However, I had a drive to build one of these beasts and felt good after it was completed. I doubt that I'll ever build another.

My health is to the point that I doubt I'll ever use it (I might need to get out of 7.5" all together), but I am talking to the Bedford & Billerica historical group about donating to them as a working display.

Any interest out there to see photos of my stub double-slip turnout with three of the four paths dual gauge (4.75 and 7.5)?

I will second that. I love photos of track work.

I can see why the Bryant did not become popular. Hard to figure out how it operates, or if it had any useful advantages. I guess being able to "trail through" with only a "bump" and not a derail would be an advantage.

Over at the NGDF, there is a long and interesting discussion on stub turnouts. In addition to the standard stub and the stub double-slip I built. A fellow posted a photo of the SPNG in Laws CA when the stub turnouts still existed. The photo shows a a right hand stub facing away from the camera connected to a 3-way stub going under the camera. The short length of stub rails are only held in place by gauge bars and it appears to by a 6-way connection whereas the double slip is "only" a 4-way connection!

Subject: Compounding debate



Hi all,

The conversation around the lunch table turned to the viability of compounding this last Sunday.
Someone had mentioned a South African Garrat was successful with a firebox reheater for steam travelling between cylinder sets, while someone else voiced their doubt at the viability of compounding given we are restricted to 100psi here in NZ.

There ensued an interesting discussion, but it was all second-hand expertise as none of us has built a Garrat or Mallet or any compound prototype that would demand the decision.

So I wondered what experience members of this forum may be able to draw upon and extend my knowledge on this very interesting subject?

Does not pertain to Locomotives...
However, in the power plant idustry new plants have been built with Reheaters;
Whereas the Exhaust steam from the Seam Turbine returns to the boiler, makes a few passes through and then gets combined with Intermediate steam and returns to the Steam Turbine...
For what that is worth...

i saw a compound at a meet once. he had problems with the high pressure engine slipping a lot before the low pres. ones got going. he ended up adding a chain drive between the 2 engines to force them to work together. the engine never ran at the meet so i cannot comment on that.

The prototype also had the same problems until the low pressure cylinders had steam in them.

Many prototypes handled this by using a by-pass valve to the low pressure cylinders injecting high pressure steam direct until both engines were working. It worked as two simple steam engines.

Once the locomotive was moving, the bypass was shut off and the locomotive then worked as a compound.

Subject: Re: Compounding debate



Compounding puts a large load on the engineer to balance power until everything is warmed up and then the savings starts. Managing high pressure bypass to the second stage must have been a real art for the engineers.

I think the only compound engines that really worked were the inline and parallel compounds on each driver.

I did see several compounds running on labor day at Old Thrashers in Iowa. (none on locos) Very impressive stationary Coreless 16"/36" bore and several steam tractors.

The K1 - the original Garrat built for 2ft Tasmanian Railways had a simpling valve for starting too. Aparently crews liked it becuase it was very sure footed. If the high pressure set let go the intermediate pipe pressure would rise and settle the engine. If the low pressure set let go the pressure would quicly drop and therefore also settle the engine. The loco was 35 tons and could pull 150 T of train up a 1 in 27 grade (27%) while negotiating 1 1/2 chain radius curves (30m or 90ft)

Subject: Re: Re: Compounding debate



Chris, I think if you recalculated the percent of grade you would come up with 3.70% not a 27% grade which would require a rack type locomotive to climb. Percent of grade is the amount of rise or fall vertically from level in a horizontal distance of 100 units. In your example the 1 in 27 would be how many times 27 goes into 100. On radius 1 1/2 chains would be 99 ft. as a chain is 66 feet long and each link in a chain of which there are 100 links are 7.92" long.

I question how practical compounding is on our scale model engines. It really was not all that practical on full size locomotives. Look at how many were converted back to simples.
Besides the starting problem on articulated locos we generally do not have enough superheat to prevent condensation in the low stage cylinders especially since we run a steam pressures much lower than full scale.. Has anyone ever tried to build a fake compound? Bush down the large low stage cylinders to the same bore as the high stage cylinders and plumb it to run simple. It would still look like a compound but without its problems.
I do not know if this would solve the starting problems.
Just an idea!

I think you have summed up the sentiment of most of the regular Winter Creek crew. the net effect is then to size the boiler to run four cylinders instead of two I guess.

As I recall (I might not have this correct), During the late 1940's when PRR was experimenting with unusual steam configurations (4-6-4-4, 4-4-6-4, 6-4-4-6, etc), PRR came up with an automated "switch" to change from high pressure to low pressure steam automatically. As with so many items this late in steam development, the idea worked but there was not enough time to work out the minor bugs to make it a slam dunk befor diesels came.

If I could recall where I read this, I'd look it up to be sure. I think it was in the PRR Q2 4-6-4-4 book.

The PRR Q2 was successful enough that the PRR canceled 26 4-10-2s (I think) and built 26 Q2s (c1947-1948). If steam had continued it is believed that this (especially with La Porta's innovations added in) would have been like the Lima Super-Power was earlier in the 1900's.

For what it's worth.

Subject: RE: Compounding debate



Taking a quick look at my T-s diagrams for water (steam) tells me that a compound 'should' work at 100psi (8 bar) operating at a temperature of 250 C if the exit pressure of the high pressure side doesn't drop below 4 bar and is reheated to over 200 C before entering the low pressure set. It's that reheat stage that is so critical when operating close to the saturation line. The low relative speed and power that we tend to operate at actually complicate boiler management in a compound loco. Is anyone aware of a true compound that was used in high speed mainline service? All the examples I'm aware of were used in slow speed helper service.

Roy,

You probably want to look at Chapelon's work in France for high-speed compounding. There is a discussion and locomotive comparisons in the English edition of his book "La Locomotive a Vapeur" chapter 12. He gives a chart showing steam consumption figures at 150 and 300 rpm of his 141P 75 (a 2-8-2), the Pennsy T1 and a few others. Interesting reading.

Hello all, and apologies that I've been absent for a while....

I'm regularly at the Moors Valley and can measure coach (car) dimensions as you need (I'm there most Tuesday evenings, including this week). The coaches are (roughly) 8ft long and come in two widths - 24 inch and 26 inch and have a slab of concrete cast between the bogie centres. All have a long centre seat and in the last few years have had truss rods added to increase stability and prevent overturning in an accident. Check out the photos on the website, though these don't show the truss rods.

http://www.moorsvalleyrailway.co.uk/

My own loco has been out of service whilst we try to cure a persistent habit of de-railing. It visited the nearby Eastleigh Lakeside Railway to be weighed on their weighbridge and have some other suspension modifications and is now back home. With luck I should road test it in the next week or so and hopefully it should be ready for traffic. There is some YuTube footage worth seeing of ist holiday at Eastleigh however at:



and also

http://www.youtube.com/watch?v=WpE6EOMES9o


which proves the loco actually works! There are other youtube clips showing the recent "Garratt Gathering" at the Moors which included the scale model of East African Railways No 5918 "Mount Kilimanjiro" a 4-8-2 + 2-8-4 Garratt: all 18 feet of it!! Start with this clip and check the related clips (we also had an "American Weekend" in the summer):



Let me know if you need any measuring done or "Moors Valley" quesitons answered.

Subject: 2.5" Scale drawings & Parts



Hello All

My name is Michael Barnard; I currently live in North Georgia in a small town called Chickamauga. (Site of the famous Civil War Battle) I work full time for the Tennessee Valley Railroad museum and I am a licensed steam locomotive engineer. About 30 years ago I build a 1.5" scale bobber caboose and gondola. I also had about 200' of track but never got a locomotive.

A friend of mine through the RR museum is building a 1.5" scale 2-8-2. He has done a beautiful job with it. I am really impressed especially since his profession was accounting and a musician. He knows that I am interested in such things, so we have been talking about me getting involved with such a project.

I am in the process of raising the money to buy a metal lathe and hopefully will have it before Christmas. While I like 1.5" scale, I really don't like ridding on the locomotive. I would rather ride in the tender so to speak. I guess that comes from operating real ones everyday.

I was thinking about building a 2-4-4 in 3.75" scale, but it would be very big and expensive. So now I am exploring the possibility of 2.5" scale. I have thought about building a reasonable replica of the EBT M4 that would be battery powered. There would also be a flat car or two and a bobber caboose. That would get me going with something to tinker with at the club track in Dunlap TN.

What I really want to build is a steam locomotive. It could be something as simple as a 0-4-0 tank-mining engine or a 3-foot gauge 2-6-2 like the EBT's number 11.

What I need help with is fining some prints for something to build and a list of suppliers. I have found suppliers for couplers and other misc. appliances, but none for a steam locomotive kit and or drawings and castings.

I was hopping that with all the expertise on this group that some individuals could point me in the right direction.

Thanks for your input
