2.26.0 Release

Changes

better electrified railtype compatibility for electro-diesel (bi-mode) vehicles
- these vehicles should now use 'electrified' power and visual effects on a wider range of electrified railtypes
- previously they only worked correctly for railtypes with 'ELRL' label

2.21.0 Release

Changes

added Restaurant Cars
- adding a Restaurant Car to a train will provide a bonus: improved run costs and payment rates for all Passenger Coaches and Luxury Passenger Coaches in the train
- the bonus reduces run costs for those coaches by 70%
- the bonus increases cargo aging rate for those coaches by 30%
- the bonus is applied once only per train, adding more than one Restaurant Car will have no additional effect
- the bonus applies only to Passenger Coaches and Luxury Passenger Coaches, not railcars, high-speed trains, mail vans etc
- the bonus can significantly improve profits on some routes, but Restaurant Cars are expensive to buy and run...it's up to you to decide if they're worth it ;)
rebalanced Passenger Coach and Luxury Passenger Coach purchase and run costs
simplified cargo aging for passenger vehicles
- Passenger Coaches are unchanged, with faster carging (roughly every 0.75 days)
- Metro trains are unchanged, with very fast cargo aging (roughly every 0.47 days)
- all other passenger vehicles now use the same standard value for cargo aging (every 2.5 days), where some previously had slower aging rates
- this change simplifies balancing between passenger vehicles (and makes maintenance of the grf easier)
- gameplay effect of this change should be negligible in most games
renamed Luxury Railcars to Express Railcars
minor tweaks to purchase costs of Express Railcars, Express Railcar Trailers and Railcar Trailers

- increased Triton power to 7200 hp
increased Revolution run cost, to account for high power in electric mode
adjusted railcar tech tree
- Zeus changed to electric power, not electro-diesel, hyrid power has limited gameplay benefit for the general-purpose passenger railcars

- increased Pylon diesel power to 700 hp
- added Cargo Sprinter diesel freight railcar
  - 99 mph, 1650 hp
  - express cargo refits (mail, food, engineering supplies etc)
  - for increased capacity add Express Container Wagons, these match Cargo Sprinter speed, and will also match appearance
  - other wagon types can be added, but might not match appearance or speed
- Bright Country luxury railcar adjusted to electro-diesel
  - 620 hp of diesel power
  - experimental idea, this may be of limited gameplay benefit
  - intended use is long routes that are partially electrified, with lightly-trafficked non-electrified sections, but eh, try it out
increased capacity for standard Passenger Coaches
- significant bump to these, e.g. 12 pax -> 16 pax in early game, 48 pax -> 64 pax in late game
- similar increases also applied to railcars, railcar trailers and hst coaches
- should aid gameplay with highly-connected cdist networks which tend to require high passenger capacities
- Luxury Passenger Coaches unchanged, these match closely to original TTD capacities
added Bolster Wagons,
- looks like a flat wagon with side stakes
- refit to 'long products' and metals industry cargos, e.g. steel, copper, aluminium, pipe, wood etc
changed Stake Wagon to Timber Wagon
- removed pipe refit, now wood only
added Sliding Roof wagons
- same refits as Tarpaulin Wagons
- cargo visible during loading
repainted Tarpaulin Car (again) to use company colour tarpaulin, the previous white/grey version just looked odd
added Twin variant of Sliding Wall Vans
- these are non-standard 10/8 length
- articulated so can't be flipped to change livery
- bit of realism eh? :)
added Low-floor Container Wagons
improved appearance of cargo sprites for logs
added slab cargo sprites for carbon steel

Fixes

container wagons weren't showing tail lights
autocoach was using diesel engine sound effect and colour scheme, now uses steam engine sound effect and colour scheme

- added 2 'wagon base colour' parameters - optionally set freight wagons to use fixed colours instead of company colours, even in groups with colour schemes
- added 'wagon colour randomisation' parameter, offering 3 options for randomising the colours of freight wagons
- these apply to most freight wagons, with some exceptions, for example, brake vans, mail vans and passenger coaches
added a new 'Outrageous' option to 'train capacity' parameter, providing 77% increase of default vehicle capacity
added descriptions and '(default)' labels to parameters where needed
renamed Coil Carrier to Covered Coil Carrier
added a new uncovered Coil Carrier type with visible cargo
improved sprites for
- Covered Coil Carriers
- Tarpaulin Wagons

Codechanges

fixed rendering of vehicles cargo pipeline when MP pool isn't used
refactored some switches so nml can automatically optimise them to constants when appropriate (glx)

2.11.1 Release

Changes

default for 'Random Wagon Colour 3' should be company colour 1, not company colour 2

2.11.0 Release

Changes

experimental 'Random Wagon Colour' parameters
- freight wagons will randomise to 1 of 4 colours when built
- players can use the parameters to control these colours
- options for specific colours, or company colours 1 and 2

Changes

alternative liveries for some company colour combinations
- more information in html docs https://grf.farm/
increased gen 5 freight speed to 87 mph
cap gen 6 freight speed to same 87 mph, as the forced gen 5->6 transition is low yield for gameplay interest, and should be optional
- this also means that some gen 5 engines remain relevant for gen 6;
- increased gen 6 wagon capacity and reduced tare weight to reward upgrading if players want to take the option
increased gen 6 railcar speeds to 99 mph
extended model life for Gronk! type engines
added a trailer car for High Flyer luxury railcar

Fixes

haulage speed bonus calculation was broken, causing electric railcar default speed to be too high
HST coaches were too heavy
adjusted HST coach buy cost to be about same as luxury passenger coach
removed alternative company livery option that was added for certain wagon types in 2.3, on reflection it was a flawed idea

- don't use directories as dependencies in Makefiles
compile optimisation for speed and filesize
- save 5k realsprites by setting purchase sprites to [] when no realsprites is needed
- set additional grfcodec container and compression options in makefile
- forcibly suppress animated pixel warnings
- remove around ~7k duplicated realsprites by only providing 4 realsprites for some symmetrical 8/8 vehicles

2.0.0 Release

"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
engine roles depend on OpenTTD setting 'Enable wagon speed limits: On'
- without this setting Iron Horse 2 works fine, but some freight engines will overlap general purpose / express engines
greatly expanded range of vehicles
some Iron Horse 1 vehicles have been kept, with new stats and sprites, all other vehicles are new
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'

Engines

added wider range of low-power, medium-power and high-power engines
- Iron Horse 1 had gaps where there wasn't really an appropriate engine for some routes
- medium-power engines were especially lacking in Iron Horse 1 after 1935
electric engine roster expanded to 16
- 12 electric
- 4 electro-diesel (bi-mode)
- first electric engine available around 1905
- Iron Horse 1 included only 4 electric engines

Railcars

expanded railcars to 20
- 16 standard gauge and 4 narrow gauge
- Iron Horse 1 included only 3 railcars
dedicated variants for
- passengers
- mail/express freight
- Iron Horse 1 relied on refitting passenger railcars to handle mail/express freight, which was faff, and can't be used reliably with auto-refit in stations
added electric and electro-diesel railcars
first railcars now available around 1925
railcar appearance will automatically adapt to consist, creating single cars, or multiple-unit trains

High Speed / Very High Speed Trains

added dedicated high speed and very high speed trains
fastest train in Iron Horse 2 is 186 mph (Brenner, available around 2018)
- 155 mph Screamer from Iron Horse 1 is removed, these trains replace it
maximum speed will only be available with dedicated passenger coaches
first high speed train available around 1980
first very high speed train available around 1987
very high speed trains include
- distributed power: all coaches are powered
- tilt bonus for faster speed through curves

Wagons and Coaches

added wider range of wagons and coaches
- Luxury Passenger Coach
- Express Van
- Curtain Side Van
- Sliding Wall Van
- Tarpaulin Wagon
- Coil Car
- Plate Wagon
- Stake Wagon
- Coal Hopper
- Mineral Wagon
- Chemicals Tanker
- Cryo Tanker
- Grain Hopper
- Fruit & Vegetables Van
- multiple lengths for wagons and coaches, increasing visual variety
some Iron Horse 1 wagons are missing from Iron Horse 2, but will be restored in future when sprites are finished
- Intermodal Flat Car
- Metal Car (torpedo wagon)
- Supplies Car
- Vehicle Transporter Car
Combine Car is removed permanently, as it cannot work with OpenTTD autoreplace
passenger coach and mail van appearance automatically adapts to consist
- alternative liveries depending on attached engine
- sprite variants such as brake coaches, restaurant cars, post office vans as appropriate

Narrow Gauge Trains

simpler but more useful narrow gauge engine roster
expanded narrow gauge railcars, first available around 1950
expanded narrow gauge wagon and coach types
narrow gauge engines and railcars are somewhat 'inspired by' French and Corsican trains, as British and Irish narrow gauge is more limited

Metro Trains

sprites redrawn
minor stats adjustments

Improved Visual Appearance

reworked all sprites
added multiple livery options for many vehicles (random, or when vehicle is flipped in depot)
all vehicle lengths now 4/8, 6/8, 8/8, 10/8, or 12/8
- easy to make exact tile-length trains if desired
depot flip enabled for many vehicles (was disabled in Iron Horse 1 as a side effect of how vehicles were coded)
more accurately positioned visual effects
rear lights on consists
electric vehicle pantographs are raised on electric rails, otherwise lowered
doors open on many vehicles when loading/unloading

Cargos

updated cargo support for FIRS
improved assignment of default cargos for wagons (noticeable when using different climates, industry newgrfs etc)

Docs

improved display of trains
better navigation
added a basic gameplay guide

Translations

default translations now appropriate to British English (previously used US English)
multiple languages updated

Codechanges

reworked Makefile and general approach to compiling
improved compile speed, including very fast compiles if only sprites are changed
removed the requirement that all vehicles are articulated (was used to support vehicles with sprites longer than 8/8)
reworked graphics generation
- automated buy menu sprites
- automated cargo sprites
- automated chassis and roofs
- automated pantographs
added shared library of cargo sprites, cargo refits etc with Road Hog and Unsinkable Sam
refactored classes and templates
simplified vehicle definitions, removing boilerplate and redundancy

Known issues for 2.0.0 release

there may be a period during 1860s when engines are available, but no suitable wagons (or wagons but no suitable engines), this is due to randomised vehicle introduction dates and will be fixed in future
loading speeds are unbalanced, and some vehicle types may load too slowly or too quickly, this will be fixed in future
electric and electro-diesel engines might behave incorrectly on electric railtypes where the label isn't 'ELRL', this may be fixed in future
Iron Horse 2 grf and docs are not published on #openttdcoop bundles server, this may be fixed in future
Brenner cab doors do not open when loading, this will not be fixed

weight was too high for Slammer and Tin Rocket, now reduced
Tin Rocket HP reduced in line with reduced weight

1.9.0 Release

Features

rename the 'Brit' roster to 'Iron Pony'
added 'Longwater', 'Tyburn' and 'Tidewater' metro freight units
removed 'Mole' metro locomotive and metro freight car

- lower power, but with very low costs
- with no wagons attached, Cargo Sprinter will reach top speed quickly
- 1 or 2 wagons can be hauled per Cargo Sprinter, but acceleration will be slower
- add as many Cargo Sprinters to the consist as you need, they're affordable
add vehicle transporter car (no cargo graphics yet)
covered hoppers now refit to rubber cargo
