Here's the "it."
This specific complaint has come up before.
Over time, the same complaint (not just this one) is going to have the same effect as repeating the same joke.
The joke is funny the first time.
The 10th time, it gets annoying.
By the 20th time, someone is going to want to slap the current joker.
Hit the 25th time, the current joker gets slapped.
And when 30 shows up, that joker gets punched.
It is a normal human reaction for people to get annoyed at the same thing when hearing it over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over, ad infinitum, ad nauseum.
Rare is the comment/item/whatever that can last long.
This is true in a LOT of places.
Yours and Anthony's comments are having that effect.
I think the meter is at 24th time.
Besides, you have a replace tool in Surveyor.
Pick a route, put the track and the new track in the replace tool, hit a button and WHAMMO, all the track gets replaced.
Do the same with a tree (though not in a winter scene).
And for the texture (though it will look odd to replace something like snow with Gravel With Puddles).
Replace a station manually due to different sizes.
Then save and you have your route with new content.
