2 news props in the trainstation_01 and the same in the Kleiner's lab

I deleted some materials that didn't have a model on the maps so let me know if there any missing textures.

Thanks to a user posting a screenshot where I saw that the APC didn't come with the Dark Interval model, I had to update the trainstation_03 and 04 maps.

Their interior are now visible and compatible with retextures.

Combine Fabricator and crates textures have been fixed
