Work on the Central Indiana & Ohio Railroad (CIOR) is progressing well. Both mainline decks have been built and the "small helix" is complete. The double track mainline is in place from CP-Thorne (Indianapolis East side) to CP-Dunreith (Dunreith, Indiana) which is about halfway to Richmond, Indiana.
Some problems have cropped up in the past few weeks, the biggest being at CP-Riley. This area will eventually be reworked, as currently there is only one crossover there, and I need to add another. The foam method I am using (by the way this is the first time I have used the foam method) has its pros and cons. I am considering doing the top deck in traditional methods and using the foam method around that instead of cardboard strips and plaster.
The Hawthorne Yards in Indianapolis (under Greenfield to Indianapolis section) are progressing nicely. Only the staging "arrival-departure yards" have yet to be laid out. They will actually run under the Greenfield - Dunreith area, allowing us to park full sized trains without breaking them up. The pit tracks are in, and wired as is the entire yard. I decided to use Code 83 on the yard as Hawthorne in real life would have received this type of treatment due to the massive amount of freight traffic that moves through it.
The section aroud Dunreith is ready for scenery. This isn't my favorite part of the hobby, but I would like to have that area finished so I can start photography. If you are from this area, you might notice that Dunreith is missing the NKP. Well, since this is set in the late 80's I just removed the NKP north of the diamond. I left the rest in to the south for the elevator at Sexton. In this, the Sexton Branch uses one side of the helix for storage of short grain trains. The layout is single tracked from CP-Dunreith to CP-Dublin Jct.
The upper deck actually does have track down and even started the industrial area at Dublin Junction. Well, things changed and the foam didn't work to my liking so its time to redo. This will allow the top deck to stretch to two feet at this area, allowing better switching more switching. In the original plan, Dublin Junction was just a manual crossover and manual siding all the way to Dublin with a manual switch out on the main. With the redesign, I have decided to make Dublin Junction a CP and end the single track there. The west end of Dublin Siding will be left out of the interlocking and connect into the non-signalled track just west of the interlocking. I also added a CP at Dublin, this will include the east end of the Dublin Siding and include a crossover to allow movement out of Dublin siding to either mainline.
The major design challenge is Cambridge City. I swore that I would find a way to model this, but there really isn't a way to do it accurately. Since Cambridge City is on the upper deck, I don't have the room to drop the deck down without interferring with the lower deck. So, I might hold off on that for awhile. I really want to get the lower deck working without flaws before I get to involved with the upper deck.
