Trackwork

83 vs 100 in helix
Other than cost, is there a reason why one would use code 100 in a helix when 83 is the rail size entering and exiting the helix?
Just started
Today, having the day off, I started working on my layout. I was so excited to have finaly started. I did not sit and make a track plan on paper, it's all stored in the head... We'll have to see by end of day what it looks like.

Yard Design
I believe I have finally settled on a yard design off the main with an engine facility and caboose track. Your comments are appreciated. The layout is a single track, point-to-point with emphasis on switching (1940's - 1950's) with steam and early diesel.

Track spacing
Hi All-
First post here... I've seen a lot of posts related to track spacing for HO... 2" on straights and 2-3/8" or 2-1/2" around curved sections. My question is, when going from a straight to curved section, what's the best way to transition the track spacing difference?
Thanks.

Main to Turntable Track
I just received a copy of the original blueprint for the AC&Y Brittain yard compliments of the AC&Y Historical Society. What a magnificent display piece this will make framed in the train room.
Interestingly enough, I noticed something on it that contradicts information I had been given earlier. It concerns trackage leading from the main to the turntable. Brittain did in fact have a switch from the main that leads directly to the turntable. And it isn't very long, less than 500 feet. It is labeled "Outbound west turntable".

Richfield Rail Runners back "ON TRACK"
February 17th, 2011 we will be moving into our new location in Bloomington, Mn.
The new headquarters will have a crew lounge for watching DVD's & videos, workshop area for individuals to work on their projects, car and locomotive maintainence bench, and 25x17 layout room with air conditioning and heat :)) lighting in the ceiling and the walls have already been painted. The floor has been painted a medium gray too.
First things First;
Under Table Manual Turnout Controls
Yes, on the MR Magazine indexes!
They had an good article on how to build a push/pull manual turnout control that was spring loaded and had a spdt switch to change polarity in the frog. Can't find it anywhere.
Can anyone help?

Tam Valley Servos 2
Well, I got my servos installed. The first one took a couple hours I had to learn the accessories functions of my NCE PowerCab as well as the servo features. I had never used accessories before. The fourth servo took about 15 minutes to install. The programming is straight-forward once you get through the first one..
parallel tracks and atlas turnouts
I want to create a passing siding (parallel track needed) with flex track and atlas #6 customline turnouts but I don´t know the geometry of these turnouts.
How to return the diverging routes to parallel?
What type of latex caulk should be used to fasten down the track?
I used liquid nails for projects the last time, but I really did not like it very much. I liked the work time, and the being a able to adjust as I went. But some of the track came up, so iw ant to try something else. I ahve Mr. Fugates video, but I dont feel like searching throught it.
just wanted some opinions.
