New Guy - I was wondering how long it would take for the light bulb to come on. I think all of us wanted to see trains running when we first got into the hobby. I know I did with my first HO layout when I was a kids. With the room you have there is so much potential to have a great layout.
Before I started my present layout, I was lucky enough to have seen a lot of great layouts. I think John Allens Gorre & Daphetid was my biggest inspiration. There are a lot of books available with track plans and numerous model railroad magazine articles on layouts wit track plans of the layout. Nothing says that you have to use an exact track plan, but these plans can give you ideas that you could incorporate into a layout.
Here on the forum, there are a lot of photos of different layouts also. You can pick and choose different features that you may like into your own layout. When I was in the service there was no way I was going to be able to have a layout, but I did subscribe to a couple of different MRR magazines and did find things that interested me.
When I finally moved into my current house, I was in N scale and I think I pretty well did just what you did. Laid track and wanted to see trains running. I enjoyed the layout but as I have mentioned, the locomotives of the time were crude to what is available today in N scale. After tearing everything out and starting bench work for my HO layout, I did a lot of planning before starting.
A railroad needs a purpose to exist. What industries do you like?? Curt is doing a fantastic job with his coal mine, which is among many industries on his layout. The big thing years ago for mines were what was called empties in, loads out. A coal mine would be built up agains a mountain and the main line would wander around the layout and on the other side of the mountain would be a power plant. Loads from the mine would go around the layout and the loaded coal cars would be backed into the power plant. Hidden tracks in the mountain would connect the power plant to the mine. The loaded coal cars would appear in the mine and the empty coal cars that the train would haul back to the mine would end up back at the power plant.
This is just one industry idea. Do you want to model a particular area or just a railroad without any particular area in mind. It's your railroad. You can do what you want with it.
It seems you now have some interest in scenery. I figured that would come about. A little bit of scenery sure can make a lot of difference on a layout.
I'm glad to see you settling into the hobby. Your thoughts are evolving. I'm sure that you'll come up with something. With the amount of room you have, you could end up with a fantastic empire.
I have a photo of the 2-10-2 that is great. I'll post it later. When you see larger drivers on a steam locomotive, it is a good indication that it was designed for passenger service like that Pacific. Smaller drivers would indicate that it was designed more for freight service.
