"Whoa Runaway horses...Racing through the darkness....Runaway Horses."  Belinda Carlisle

2 years in the making, Iron Horse 2 is an end-to-end rework of Iron Horse.

Same focus on gameplay.

Greatly expanded set of vehicles, strongly inspired by British trains.

All sprites redrawn.

Dive in and play.

*Recommended OpenTTD settings*
- 'Vehicles never expire: Off'
- 'Weight multiplier for freight to simulate heavy trains: 1'
- 'Enable wagon speed limits: On'
- these settings are recommended, but not required

*Improved Tech Tree*
- 6 distinct generations of vehicles
- first trains introduced around 1860
- last new trains introduced around 2022
- engines now have clear roles, displayed in buy menu
    - freight 
    - general purpose / express
    - high speed / very high speed
    - high capacity urban
- some Iron Horse 1 engines have been kept, with new stats and sprites, the rest are new
- greatly expanded range of wagons and coaches
- all stats rebalanced, including speeds, power and costs
- 357 trains in total, Iron Horse 2 is designed to be used with OpenTTD setting 'Vehicles never expire: Off'

    - railcar appearance will automatically adapt to consist, creating single cars, or multiple-unit trains
