15,000 Thumbnails in my User Data/Cache...can I delete?

[girlsloverailroads2]

The thumbnails in my User Data/ Cache folders number almost 15,000 and take over 400MB of space.
What are the ramifications of deleting them? If I did, would I not be able to see (for example) a thumbnail of an asset I was looking at in my CM, or when choosing an asset from the list to use in my route when in surveyor?

Thanks for your answer in advance.

In order to see them in Cm, they need to be downloaded. If you decide to delete them they need to be downloaded again next time you check those assets.

I want to know if I delete the stuff in UserData -> cache -> libraries folder? Everything in it is just a .gsl file. I know that .gs is a script file, so would it be okay to delete the .gsl files? I believe that when you start up Trainz, it compiles a group of scripts and they go to the libraries folder.
