Oppie has already done a great job at the Steam Workshop.
Like the NL Modular Station, the NS SLT and the NS DD-AR models are never shown before and are great to finally play with. Everything is well finished.
The doors work, the destination matrix signs on the trains and you can also see people in the train. For this alone, TF2 is 10x better than TF1.
I will donate to him soon for his great work and effort.
