gm_Snowrider V3 - Night

Map name: "gm_snowrider_night_v3"

If you wan't to have the [Day] Version, you can get it right here:
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2175627255

The map is an improvised replica of the environment from the Netflix series: "Snowpiercer".
You can spawn trains and run them on the pre-made rails. The large curves allow you to use them at high speed.

================================================================= Train Alternatives:
You can use this addons as a train alternative:

CBH Trains: https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=655363484
Slig Wolf Trains: https://steamhost.cn/steamcommunity_com/workshop/filedetails/?id=116572450

(Not all are trains in his collection at sligwolf, but I am sure that you will also find trains there....)
==============================================================================


For those who are interested:
Yes, I am also working on a Train addon and maybe a Gamemode but only for Gmod 2 what also be called: "S&Box" ...
