As progress continues on Wilmington Yard I have a couple opportunities to reconfigure some of the tracks in the area.

The Essential City Yard: OP Session on a "concept" switching Layout

Hi all, friends! Last Sunday my friend Marco Trespidi, a Santa Fe fan, calls me to join a short session on his little switching layout in Milan (Italy). When we met another friend joint us, Franco “Pik” Piccardo, an HO modeler from Turin.

I must say the layout itself is worth a few words as it implements a really “minimal” approach I think can be interesting for peoples who like to check his “OP” inclination without first spend much time on a layout.

Semaphore Signals

I have been studying Semaphore Signals for potential incorporation on a layout in the future. I've come across some excellent information about operations and design among various railroads. I'm considering using primarily Semaphore signaling on my CC&CI, as a mid-60's Class I carrier, this would not be the normal system..... but I'm not a normal guy, so...

Wilmington Yard in Place

I have installed almost all the risers for the Wilmington terminal.  It has been a bit of work but I think it was better to have spent the time.  I originally planned to have the bottom of the backdrop at 49" ATF (above top of floor) and the layout at 50" ATF.  I later decided  it would be better to lower the roadbed to 49" ATF.  After trying that I decided that would create issues with the joint between the backdrop and the layout.  So I raised the layout height by 3/4".  Why 3/4"?  More on that later.

Radiai for helix

Does anyone know offhand how large a radius a helix would have to be to climb 3" in the first turn while maintaining no more than a 1% grade?

 

Thanks in advance, y'all!
