Dave, Let me describe both the current module and the `master plan' so that I can get my terminology straight.
The current module will have three parallel tracks with the two mainline tracks and a third set farther apart. Two right hand switches and a connecting track (a cross over?) will join the third track to one of the mainline tracks, forming a backwards `Z' shape. Regrettably, other than the main line, most of this module won't be useable until I finish some additional modules. Once this module is complete, anyone who wants to could add additional single track modules to extend the third track in either direction. My next module would start from the switch on the single track line and, eventually, create something similar to the Valdez Terminal starting where Airport Loop Rd. intersects the yard. http://www.alaskarails.org/historical/valdez/DM-valdez-map.jpg The top line of the backwards `Z' and any lines extending this line to the right would allow for switching in the yard without interfering with operations on the mainline. Also, anyone who wanted to add single track modules to this line would be free to do so. I have lots of pictures of the scenery in and around the Valdez Terminal (it's a lot of pine trees and gravel), but I got the tree tunnel idea after seeing this on a line in Clifton, NJ. Since it was once a two track line, I think that is was once an actual line, but it now leads only to an industrial facility that receives covered hoppers and ends at this facility. What's interesting and what proves to me that this was once a two track line is that the industrial facility is on the other side of Rt.46 and the bridge crossing this highway is dual track, with the other track still running across the bridge, whereas the rest of the line is single track. ~JJ~ --- In [email protected], "ctxmf74" <ctxm@...> wrote: > > > > --- In [email protected], "empirebuilderjjhill" <empirebuilderjjhill@> > wrote: > > Picture three parallel tracks with the third track, the branch line, set > > apart from the other two and connected to the middle track by a spur and > > two right hand switches. > > > > > A spur usually refers to a single ended track such as an industry or team > track.
