Textures much better detail. Also added a Great Northern White livery.
Train replaces streak and also freight freibox
freibox2 is a custom copy of freibox i added so to so this you would need to follow a tutotial from adding not replacing cars
This is a class 377 train from around the UK through London to Portsmouth. This train takes over from the old slam door livery and this class 377 makes the perfect and might be the only UK train mod for GTA on the internet.
MOD NOW RELEASED
This mod will contain 2 streak models. The main streak is the version in the pictures with the lights that are setup to look like the real lights from the real train. The other streak will be in a folder named streak with no light. This means its a normal model of the train but the lights are standard so basically the lights the original streak has that only come on at night.
This model will replace
Streak.dff
Streakc.dff
freibox.dff(For The back carrage)
The last carrage on all streaks should be set to freibox so the carriages look complete because if not then your left with no back to the train. This can be done in gta sa train limiter.
INSTALL INSTRUCTIONS
1. Using IMG Tool or GTA Garage Mod Manager add the import the files into GTAYou will have a choice of the train with lights or train without lights. One without lights is the normal lighting for the original streak.
