Description

This mod massively improves the simulation of the AP Class 455 and Class 456 packs, adding qualities such as visual updates, bug fixes, various sound overhauls, and much more. Lots of care and precision has gone into the features of this sound mod in order to provide the most immersive and realistic driving experience possible. There is also an included scenario for the Class 455 to make the most of the new sound improvements: 2G45 16:03 London Waterloo to Guildford.

Main Features:

  • New detailed and authentic Class 455 & Class 456 sounds.
  • Class 455 visual improvements: Realistic weathering, new window frame texture, and livery corrections.
  • Class 455 cab enhancements: Revised Southern cab textures, and new SWT cab variant.
  • Improved Class 455 physics.
  • Class 455 door bug fix.
  • Class 456 'NSE Faded 4-car' preload fix.
  • Shortened Class 455 preload names and new menu images.

For more information on the changes, please see the readme, or full changlelog provided in the zip folders.

This looks amazing. SWR cab looks so much better too, always bugged me how it looked different to the real life.
