What Era, Railroads, & Locomotives are you set on?

[SP1]

I can't limit myself to a specific era or location. I really tried it, but it doesn't work. It only leads to abandon the current layout and starting a new one and so forth. I also found out that I have no real interest in operation, repetitve switching and such. My actual approach to build a layout may sound ridiculous to you because it is just a big loop made for (model-)railfanning rather than for operation. It is made up from segments/modules that show totally different locations and eras, subdivided by viewblockers. Its the only way I found to bring the steel industry, the lumber industry, the intermodal business, towns and harbours and rural scenes onto one single layout.
