BurlintonNorthern, Welcome to the forum. I am planning to build the benchwork in 3 sections to allow it to be moved at a future date.
Time for another stupid question, but what did you mean by the requirements for the electrical gaps are different? I spent yesterday searching the internet, trying to understand the difference between DC and DCC.
DC requires dividing the layout into "blocks". Only one train at a time can be operated in a block. Reverse loops and metal-frog turnouts also necessitate gaps to avoid shorts... okay, I guess those count with the block gaps. DCC only needs the gaps to avoid shorts.
Consider creating blocks for traditional DC cab control - then later you can add DCC capability. That way you will always be able to operate in either mode - and if a visitor brings their equipment over, you can accomodate them!
On a model layout, it is the thickness of your thumb! You will occasionally have a derail somewhere, so you need to be able to gently pick up a car or engine that probably will be the middle one in a yard, or on a double track mainline. Remember to leave room for the excessive over-hang of long engines and long passenger cars going through turnouts and curves! You can't stay 'to scale' everywhere on a model layout, be practical and enjoy.
Track spacing Track spacing can vary with period. 13 foot centers were once common for yard tracks, but nowadays most roads would prefer wider separation to allow for larger cars. I've asked in another forum for this and got the answer: 1930 14-foot centers between main lines and passing tracks, and between main lines when there are two or more. Today most railroads would prefer 16-foot or wider centers. I have at my class yard 46mm spacing (1.8'') but with main line and siding 67mm (2.64''). Wolfgang
Started the build today. I started by putting 1/4" plywood on the floor and put down track. I ran out of 22" radius curved track, but was able to get half the layout down. I was able to put in the sidings. I have not purchased the turn table yet, but it looks like it will fit nicely. The best part of today, I was able to run trains. Everything ran great with the exception of the C44-9W. It was the only 6 axle locomotive that derailed. I am not sure why other than it is the only kit built locomotive I have. The SD-40-2's navigated the 22" curves and #4 turnouts at full speed without problem. The 4 axles stuff also worked well. I think once I get the remaining track I need, I will mess around with the industries a bit more. All in all, a good, non frustrating day. Here is a few pictures of the progress.
Triplex, Have you checked the curve to see if it is flat, especially at the start and any joints along the outside rail? Make sure the engine trucks will swing around enough to make the curve without hitting the shell. Track gauge OK?
I know that I am wearing out the 1 more question phrase, but I have 1 more question. How important is it to incorporate re-railers into the track layout? If they are needed, what is the best way to hide them?
You know I didn't incorporate any rerailers in my initial layout plan. But as of yesterday I began to modify my plans. I think rerailers are probably a good thing. I'm still in the track wiring phase and haven't really gotten to much landscaping, but I think I'll go back and place rerailers inside of my tunnels. There they will quietly do their job outta sight.
I don't know if it is too late to modify your plan but have you considered a cockpit style? I saw this concept in one of Ian Rice's books. Basically, you would keep the current benchwork you have and add more benchwork along the front of the layout to connect the the two sides of the dogbone. This would create a cockpit of sorts in the middle. The benchwork would be removable for easy access. Just an idea. Eric
