Re: Help what is this and how does it work?

Looks to me like a manual oil pump for the cylinders. Is there a place that you can see where you would add oil? A lot of steam locomotives have manual cylinder oilers, and they work fine. Just give them a few shots every once in a while to keep your cylinders lubed.

Re: Was there ever a NG SW1 or 1200?

Those two locomotives don't look alike to me. Are they supposed to be the same builder/model?

Re: OCME Club Suspends Public events

Can we PLEASE STOP talking about this!!! It isn't like you can't hear this same stuff on every news outlet, radio station, newspaper, blog, etc... 24 hours a day. I come here to get away from hearing about it for a few minutes and read a little bit about trains. My suggestion is to stop making comme...

Re: Mystery 9" Gauge Trucks

trucks don't look very flexible, which is probably why they had to have such huge flanges. I bought a 1/2" scale 2 1/2" gauge box car several years ago which was done the same way. the truck side frames and bolsters had all been soldered together so that there was no flexibility to them at all, and ...

Re: Drilling out truck shanks

Your cast iron coupler will break long before a 3/8" bolt will in that application.

Re: Brake System Design

I guess it depends on your system type. I was ASSUMING that you had a simple on/off brake system like a lot of steam locomotives have with a brake valve in the cab that pressurizes a cylinder or cylinders, that then applies the force to your wheels. For a system like that, I usually try to set it up...

Re: Brake System Design

That's a good starting point, but you also have to figure in the coefficient of friction for the material that you are using for brake shoes. What I've always tried to shoot for is a force that applies the brakes hard, without sliding the wheels. About 80-85% of your tractive effort would be a good ...

Re: Looking for input

Dang... You're looking for a BIG project! That would be an awesome model, but that's a lot to deal with, especially trying to run it on smaller layouts. A big club track would work fine, but probably not on most of the private tracks out there. It sure would be a puller, though. A pair of brothers f...

Re: O. Winston Link

Link actually appeared in a cameo in the 1990s movie 'October Sky'. It was a movie about boys who worked on model rocketry, but was set in a coal mining town in West Virginia, and featured several shots of the 4501, painted black for the film and lettered for the N&W. In one shot where the 4501 driv...

Re: Most cost efficient way to get steel tire blanks?

Interesting, but I believe that we are over-thinking this just a bit. The railroads were trying to maximize their longevity and lengthen the service intervals on their locomotives because they were trying to maximize their profit. Their locomotives rolled many thousands of miles over steel rails bef...

Re: Appropriate tip for Ball oilers?

I believe that what you have may be an Alemite fitting, or at least that's what we used to call them. Probably not the correct name, as Alemite is a brand. It is made to squirt oil or grease into using a special fitting that fits snug into the cup shaped head, and allow you to pump some grease or oi...

of course, my fat butt is not climbing up there to do so after words.
