UK Train Replacement Mods

Description

These mods replace trains on various UK routes with their newer or better versions. Currently, these are:
Birmingham - Crewe: Northern Class 323
Birmingham - Crewe (Evero 2025 timetable) and Trent Valley: Northern Class 323 and Direct Rail Services Class 66
Riviera Line: Direct Rail Services Class 66
All routes (except the 171 timetable for East Coastway) that use the original Tees Valley Line Class 20: replaced by the Crewe - Preston version
Great Western Express: fake Class 165 replaced with Thames Valley Branches version (GWR livery only)

Unlike some other similar replacement mods, these also change the requirements for the layers to activate - you no longer need to own the older or worse version for the better one to appear.

How it's done
  1. Edit the formation asset in the usual way - replace any file paths (usually FRMs and/or RVDs) and plugin names of the original train with the ones of the replacement train
  2. Ensure that the 'RequiredDLCPlugins' now refer to the replacement train instead of the original - this should be automatic when changing the plugin name if using UAssetGUI
  3. Edit the timetable in the same way as step 1 - here it'll just be RVDs and plugin names
    There is a downside to this approach - if you're replacing multiple trains and requirements on one timetable then only the one that comes first alphanumberically (ie smallest numbers first) will be replaced. Replacing trains without changing requirements is not affected by this.

Requirements

Refer to the appropriate REQUIREMENTS.txt file in each folder for the requirements for each mod file. You do not need all of the optional requirements.

Installation Instructions

Drag the pak files you wish to use from the zip download in your Downloads folder to one of TSW's \DLC or \UserContent folders
By default, these are "C:\Program Files (x86)\Steam\steamapps\common\Train Sim World 6\WindowsNoEditor\TS2Prototype\Content\DLC"
or "C:\Users[username]\OneDrive\Documents\My Games\TrainSimWorld6\Saved\UserContent" respectively

From version 1.1 onwards, a clearer guide for choosing the files is given. Refer to this so that you get the best experience

Additional Comments

The original 20 is still in the 171 timetable for East Coastway as I don't own that DLC and don't intend on purchasing it any time soon

Replace static 20 on TVB with newer version
Replace fake 165 with correct TVB version; the 3 car has a 166 centre car as only the 2 car is included in TVB. It is also only in GWR livery; the FGW livery is still the fake version
