Railfan1307, consider that a limitation of the application. Even if you have 24 gigs of RAM like I do, the game will not use more than 4 GB. I almost bought the Metropolitan Line at JT yesterday but bailed thinking I didn't have an SSD (it turns out I do, and Suburban Glasgow still lags...who knew?), but I decided to hold out for something else anyway.

Xcelatron54, thank you for the nice comment!! I too would like to improve the route with assets that are more realistic , but my laptop does not support that due to its low specs(4 GB RAM and integrated graphics lol!!).Every time i try to place more realistic trees and assets,my system runs out of memory even before i could save anything.That's why i had to adjust to using 2d trees.Thank you for the feedback!!! I could really use ur suggestions for building another route!!

P.S: It took me around a month to finish this!!

It's a great route with a lot of time and effort put into it.
how long did it take to make?
Here's some improvements I'd make to increase the realism of the route:
Add 3D trees close to the track doesn't have to be many and mix them in with the 2D trees, 2/3 similar tree type will help improve the look
Add fields near the towns, Playing/ Corn/ Grass fields they don't have to be massive
change some parts of the towns to custom made sections rather than using the asset block sections especially for larger towns, good way to build them is break it down into 3 sections industrial, commercial, housing

Cyclone, what you said is absolutely right.Since this is my first in creating a route on my own,i might have made a bad decision for using so many routes for this.I apologise for the inconvenience caused.Thank you for the feedback.I will make sure to follow these points for creating my next route!!!

I notice you have quite a beefy list of route requirements. If I may make a suggestion to improve the number of people able to play this, I would try to pick, at most, three or four routes to focus on and remove assets from the others. That way it's not necessary for users to buy 10 different routes to play a fictional one here.

BTW, I make this recommendation despite owning almost everything in this list (it might be worth noting Netherfield will get you the B1 and O4 locos, BTW). The only ones I don't personally own are West Somerset Railway and Settle Specials. My point still remains that I own nine of the other assets and am still not able to enjoy properly what you designed. Having to load this many assets into memory is likely to cause gameplay problems, so reducing the asset load would significantly help here and increase the number of people able to enjoy this.
