I find that even a little change of scenery can go a long way to invigorate one's interest in a layout.
Little by little, I'm changing things to make my layout have more features in common with The Put (Putnam Division of the NY Central), which is very exciting for me.
The first thing has been posted before. In the Bronx along the Harlem River, I added the Polo Grounds on the Manhattan side:
To go along with Yankee Stadium on the Bronx side:
Then, I worked on the dairy farm in the Yorktown Heights/Northern Westchester County section of the layout, including expanding the corn field and adding curve sections of track to the siding, lengthening it so it runs up closer to the barn:
Then, I replaced the Rico Station with a smaller and simpler train station, more reminiscent of the former Yorktown Heights, NY station in the Northern section of The Put:
The last change was a difficult choice because the Rico Station is, IMO, more interesting and attractive model than the above small a simple train station. However, the small simple station is not only more similar to the Yorktown Heights station, its small size works on my narrow/long layout. I will keep it for the time being, and maybe add interior lighting.
This would be a good place to show any changes you have made to the scenery and structures on your layout. Arnold
