Subject: Speeder update

Hello all,

sadly, the great time at Train Mountainn is over, and now we are on our trip south to the Bitter Creek and Western, where the speeder should be run the last time on this trip.

To show some photos from Train Mountain and to report what happened since my last mail, I updated the ramble-page.

Full size plans for the D&RG C-16s are avliable from the "John Maxwell Collection"


If your considering a 2.5" scale model then I would highly reccomend the Conway Locomotive C-19 castings as a starting place.

The Conway plans are now largely available through Coles' Power models, as will, I understand, the castings for a C-16. Try www.colespowermodels.com .

Subject: Update for the speeder page

Hello all,

this is the latest information about my Speeder tour before I send it back to Germany.

Sadly, I had a bad derailment and wasn't able to run until we left the Bitter Creek & Western.

Quick update on my rash promise to post the 3/4 size 2 footcoupler print.
I've made a semi-serious shackdown of the closet with a wild variety of prints/plans/sketches. Aside from becoming reaquainted with a lot of "stuff" that has been forgotten, no luck on this first winnowing on finding the coupler drawing.

If, on the other hand anyone cares to know how the Maine Central shops lettered the SR&RL boxcars, that was one of the prints that showed.

Subject: Back home again

Hello all,

after a couple of days of recovering from my trip I would like to let you know, that I returned safe home last tuesday.

The Speeder also is back in Germany, was yesterday afternoon released by the custom and should arrive here next week. I hope, it will have not as much damage as on the trip to the US.

I would like to thank everyone, who worked for this great events on the different layouts. It was amazing to be their and to run my Speeder.

Thank you very much to all

Glad you made it home safely. Susan and I also enjoyed the chance to meet you in person at Train Mountain and Bittercreek. (We no doubt passed each other at Train Mountain in 2000, but back then only had GSQ and were running in different circles).

Hope to see you the next time you come to the US.

My friend Tony Gosling was kind enough to send over some pixs from their recent Hemsby Week Meet in the UK.
This meet was held the end of May and from all indications they all had a grand time! If you like to meet both Tony Gosling & Mike Johns who are in two of the pixs, make plans to attend BCSME's "Train Festival 2003" August 8th-10th 2003. Burnaby, B.C. They are!

Subject: Track strength

Hi Folks:

Some time back, there was a discussion about track, tie spacing, etc. I've uploaded a photo into the "files" showing a four-wheeled "Heywood" style wagon on the 7-1/2" gauge Eskine Tramway. The photo shows a load of 20 concrete retaining wall blocks and the 100 pound car, for a total of about 600 pounds, with one wheelset directly between two ties. That would be a load of about 300 pounds per axle. There was no noticeable deflection in the rail. For reference, the rail appears to be (it's third hand to me, so I can't be sure) "West Coast" pattern, 1" high, with 18" long 2x4 ties on 10-1/2" centers.

I have just posted pixs from Kitsap Live Steamers Friends & Family Annual Meet. Weather was outstanding for a ride through their beautifully forested track. Cheryl McInnes & fellow KLS memebers afforded us all a great tasting BBQ meal for Dinner.
The turn out was good with trains running all day long, glad I was able to attend!

Subject: A new member and a question re snifting valves

Hi to everyone,

I'm new to the group and I have a question for the members.

By the way of introduction, my name is Tim Couling and I'm building a 7.25" engine which will be based at the Moors Valley Railway in Dorset, UK. The loco is loosely based on the Keny-Uganda Railways EB3 class, later East African Railways Class 24. It is not a scale model, but in common with the other MVR locos uses the prototype as inspiration for a "narrow gauge" loco where the driver sits in the cab.

I have created a folder in the files section where I have put an artists impression of the loco and a pic of the prototype. I'll add other images as construction progresses. The valve gear is now complete, and hopefully I'll be testing the loco on compressed air in about two weeks time.

The question:

Snifting Valves: The cylinders are 4.25" Stroke, 3.5" bore. Main steam pipe is probably iro 3/4" bore with BSP thread. The loco will not be superheated and fitting will be placed after the regulator valve but before the header. Do any members know of a suitable "off the shelf" snifting valve suitable to sit on the top of the smokebox? What I have in mind is something like the MeLeSco type (Locomotives & their working, Vol 1, p126; Simpson & Roberts; Virtue 1952), which I could manufacture myself as a last resort if nothing close is available.

Any help gratefully received.

If anyone would like the critical data for the loco I'll post it here when I add the latest construction photos later this week.

Regards and thanks,

Subject: Re: A question re snifting valves


On the K36 I used a standard vertical pipe non return valve about 1/2 BSP. These were situated on the steam chests. Howver I don't see any problem with where you put it as it is all bronze construction. (i.e. no bits to melt!)

To make it look good you can machine the top and make a simple vent as a fancy cap. If your interested I can look it up in a catalogue say RS and give you the part number and exact specification.

I assume that is one of the loco's in your workshop?

Good Luck.

2x4's vertical ie: long end up? I've made some display track using treated 2x2's ok for storage sidings but my optical engineering (if it don't look right, it ain'i) wouldn't put it on the main.

Subject: Re: Track strength

Hi Cam:

No...2x4's "flat", the wide side up. It looks like current practice English 15" gauge track....except the rails are kinda' light for that, they generally use some pretty hefty stuff. The ties I stripped off the "panels" are 2x2's, 14" long. The track looked like standard gauge track....in a photo...but in "real life" it didn't. Besides, that extra 4" of tie length gives the track a lot more stability.

Subject: Re: A question re snifting valves

Re Part Number: Yes Please!! I can do the machining to make it look good if I have a basic part to work from. I have about 1" vertical space to work in between the steam pipe union and the top of the smokebox, so a part about 1 1/2" long would be about right (ie one end would sit just proud of the smokebox and allow the fitting of a decent sized cap.

Sounds as if you were at the American Weekend we held recently? Mine is the loco without the cab, furthest from the turntable. I machined the RH side Expansion Link the week after you saw the loco, LH side last week. I'm working on the combination lever pins, Cylinder and Steam Chest gaskets this week. Should be on air next week or thereabouts.

More photos posted by Wednesday.

Regards and thanks,

Subject: Re: A question re snifting valves


I have had a look for one but nothing has turned up. If you go to a good plumbers merchant you should be able to get one. ]

What you are after is a vertical check valve (not spring loaded) you should be able to shake it and hear the valve rattle inside. They work very well and come in a range of sizes. Make sure when you make the vent cap that you allow enough holes for the vent otherwise if it's not equal to the flow through the actual valve the valve will not close off when the steam is admitted to the cylinders.

Yes I bought my K36 down for that weekend.
When I get a chance I'll post some pictures.

Good luck, when you have it running let me know and I'll pop down.

Subject: Re: track strength question.

I remember that the Los Angeles Live Steamers investigated track strengths many years ago and for 7.5" gauge imposed a limit of 425lbs per axle (on nominal 1.5" scale passenger car wheels). Locomotives were allowed heavier alxe loadings depending on diameter. That was when they were using nominal 1" high rail in 6061 or 6063 Al. Alloy heat treated. Now they are using 1" nominal height steel rail on plastic "2x4" ties set with the narrow edge up and ballasted with Decomposed Granite (dirt). They are expermenting with gravel ballast but no decision yet. As Steel is about 3 times stronger than the Al. Alloy, I would assume that the axle loading eventually will be raised.
I hope this information is of help.

Evening All,

I've just added the first photos of my 2-8-0 loco "Athelstan" to the Files/Athelstan section. Please take a look and let me know what you think (honestly).

The motion is now assembled compeltely to the lifting link, though the keen eyed will note that the steam chest covers are missing. The covers will be fitted tomorrow once the timing has been checked.

Subject: Rail Zeppelin

Greetings from Torrid Tacoma! (95 degrees, and no "Aroma" to speak of, thank God!)

Because I grew up playing with Marklin trains, my interest and passion seem to lie with the DeutscheBahn, I was wondering if anybody had any additional pictures or information on the Rail Zeppelin prototype, circa 1925. Due to the uniqueness of the prototype (its source of motive power was an aircraft engine coupled to a four-blade propellor) I thought that it would make for an interesting speeder.

Although Marklin's HO model does make for an interesting conversation piece on a model layout, there are several major differences between the prototype and the model, like length and wheel arrangement. Even though it was a "one hit wonder" I would prefer to build it as close to prototype as possible.

Any information (like dimensions, pictures, etc.) would be GREATLY appreciated.

hallo erik
just a hint - there have been nice pictures for very long time ago in merker & fischer eisenbahnmagazin.
unfortunately this german mag has not been issued on cd-rom so far - as it is miba.
the wheel arrangement of the maerklin is absolutely correct - 2 wheeler only with a very long wheel base.
