I've taken pictures of objects used for transit ties before:

I prefer using Krytoxå¨ grease made by E.I. du Pont de Vours... not cheap but a little goes a long way and it is inert.

I believe RR curves are defined mostly by degree using the chord definition. Highway curves are usually defined either by degree (arc definition) or r...

Yes, you do need both horizontal transitions and superelevation ("banking") to handle the acting centrifugal and centripetal forces properly. Going fr...

If I ever built my own model RR layout, I would spirallize it for authenticity, increased running speed, and because I just plain like spirals.

I wonder if it would be possible to build model railroads with transition spirals? Do they make track where you can possibly do so?

Hmmm... a 131-foot radius calculates to somewhere around a 44-degree curve, and a 57å¡ curve is only about 104.79 feet by chord definition... somethin...

We mainly use machetes. On occasion we will use loppers as needed, and if blackberries are really, REALLY thick we use the gas-powered trimmer.
