You mean 1944? This was a 1938 photo. The schematic I have for 1961 showed an interchange with the B&O and that looks like a track there. The photo actually blows up much larger, I just needed to fit the layout in one screen.

I'll try to remember to blow-up and post that area.

1st) Where are you finding the photos?

2nd) The Old Dog just found it interesting that Indiana, Pa was NOT listed as an interchange it that source. My understanding is that having an interchange requires the agreement of both RR's to exchange cars at that point. The existance of a connecting track could merely mean that there was a connection to allow emergency detours or that there was a switching district that allowed both roads to serve certain customers.

Have fun

Dog,

I reaaly looked at the large photo and I have come to the conclusion that you are right. The track never actually joins between the two railroads. They cross. They run parallell with in yards, but I can't see a way of getting a car from one track tothe other.

I prefer my challenges to be more related to car order and efficiency of switching, if that make sense.

If you think of a Timesaver as a runaround with a spur on one side and a switchback on the other, it ceases to be just a puzzle.  Hopefully you can find some IRL trackage that could be cut-and-pasted into a similar configuration.

I think you make sense - you like to sort out the cars so you can deliver them with minimal fuss, not get trapped in confined spaces making the delivery.

From experience: in 6 ft long, the interchange track is the one that stops at the cliffedge, rather than at a bumper post.  When I design and build a few cassettes, cars can start arriving/departing without use of my 0-5-0.  Alas I cannot think of how to model both ends of an interchange track, plus do anything else, in the space.

Other research possibilities: (a) If you want local industries and not so much specific locations, can you find a phone book for the area?  Use whatever businesses sound good until better information comes up.  (A piano maker drew my attention - my wife can play.)  (b1) See if the city's Chamber of Commerce has anything historical.  The 1907 version of Ft Wayne CoC was called the 'Commercial Club'; there are probably more synonyms to check out.  (b2) Visitor and Convention Bureau(s) may also have something you could use as a start.  (b3) Tourism agencies need sponsors; if they are not all insurance agents you may have customers for a team track.  (c) The old mine companies (or their successors) may have brochures &c touting how easy it is to get shipments via the railroad, which may offer useful details.

Modeling 1900 (more or less)

I tried a timesaver online once. I found myself see-sawing back and forth with cars on both ends trying to get that one shuffled out of the deck so I can finish the resulting Rubick's cube.

I suppose im laying my track in a manner that supports one way switching instead of a puzzle palace.

I finally solved it but took me weeks. Everything has to be done in a certain order to make it happen.
