Series 9.7


Released on August 9th, 2015 for Minecraft 1.7.10.

  • NEW: Steam Locomotives can now pull fuel and water from attached carts.
  • NEW: Rewrote the entire system for moving items and fluids around within Trains. It should be more compatible and less buggy than the previous system.
  • INFO: The way the system works is that push and pull requests can only pass through carts that allow them to be passed. For example Chest Carts can pass item requests, but not fluid request. And Tank Carts can pass fluid requests but not item requests.
  • INFO: Because of the way the system works, you can either attach a Chest Cart to your Steam Locomotive to supply fuel or a Tank Cart to supply water, but not both. Choices are good.
  • NEW: Sneak-clicking with a Surveyor or Tuner will now clear the current pairing operation.
  • NEW: Redesign Tuning Aura and add Surveying Aura for the Goggles. Should be more visible now.
  • NEW: Add Signalling Goggle Aura, a combination of the Tuning and Surveying Aura.
  • FIX: Rock Crusher can now crush Entities again.
  • FIX: Disabled Tile Entity caching on Bukkit. Bukkit doesn't seem to invalidate Tile Entities correctly. This is likely the cause of most issues with Multi-blocks on Cauldron. Sadly, caching is a significant performance booster when it works.
  • FIX: Detector and Directional Detector Track should wait a few ticks before turning off the redstone. Helps prevents pulsing while trains pass over, which often led to glitchy railway logic.
  • FIX: Make Receiver Boxes occasionally update their neighbors to prevent situations where the Receiver says one thing and attached blocks another. Could happen when the Receiver was in a different chunk from the adjacent block.
  • FIX: Have Block Signals save the last known position of track end positions to NBT. Should prevent Signals from returning Yellow if the chunk on the opposite end isn't loaded. May cause traffic jams and collision if your trains don't have Anchor Carts.
  • FIX: Increase the area that Anchor Carts keep chunkloaded from 3x3 chunks to 5x5 chunks in order to help reduce chunkloading derived issues for moving Trains.
  • FIX: Boilers and Hobbyist Engines should defer water triggered explosions until their own update tick. Should prevent other mods from crashing when their block randomly disappears mid-update.
  • FIX: Disabling any blocks or items used in Rock Crusher recipes should no longer crash. Issue #602
  • FIX: Prevent Locking Tracks from reseting in the middle of a Train by searching for nearby carts that are 'almost' on the track.
  • FIX: Fix various issues with Signal and Controller/Receiver pairing that could result in dropped links and other random bugs.
  • FIX: Fix NPE in the Signal debug statements.
  • FIX: Fix minor issue with Energy Loader's IC2 integration.

Series 9.6


Released on April 26th, 2015 for Minecraft 1.7.10.

  • FIX: Dupe bug with Fluid Container code.
  • FIX: Fix the edge case where a Signal is loaded but the nearest Track is not causing the Signal connection to break.

  • NEW: You can now reset the Signal Tuner and Signal Block Surveyor by sneak-clicking.
  • NEW: Add Passive Anchor, does not force load chunks on game load, only when visited. Recipe uses Cyan Dye for now, but will eventually use Prismarine.
  • NEW: IFluidContainerItems should be completely supported now.
  • NEW: Add Debug in-game command that will dump data to the logs.
  • NEW: Capacitor Boxes now have a switch to determine if they should trigger on a rising or falling signal. (contribution by wshadow)
  • NEW: Improvements to the Switch code that should make them more reliable and predicable. (contribution by ssotangkur)
  • CHANGE: Loaders "Has Work" Buildcraft trigger should better reflect the actual loader status. Issue #535
  • CHANGE: Signal Block Relay Boxes now require two Signal Circuits in the recipe instead of just one.
  • CHANGE: Signal Block Relay Boxes no longer function as a Controller. If you need that functionality, put a Controller Box next to it. May break some setups.
  • CHANGE: Improve Signal Block debug print statements to help with debugging some possible issues.
  • CHANGE: Coke Block now 10x Coal Coke fuel value and is flammable. (contributions by daniel and Kamran)
  • FIX: Various chat messages that didn't before should now properly localize.
  • FIX: Personal Anchors should only tick their update (and fuel use) function once per tick...oops.
  • FIX: Fix Geode Generator. Issue #576
  • FIX: Geodes should only spawn under the ocean floor now, instead of half submerged. Issue #526 (contribution by liach)
  • FIX: Melt snow on top of Smokers. Issue #530
  • FIX: The Controller Box shouldn't respond to redstone signals that don't update it. Issue #539
  • FIX: Tanks should now properly sync with the client again. Issue #545

  • FIX: Fixed NPE when breaking a cart on a Routing Detector. Issue #562
  • FIX: Engines should output to IEnergyReceivers in addition to IEnergyHandlers. Issue #564

  • FIX: Fix stack-over-flow on circular Train.
  • FIX: SMP block sounds should work now (contribution by PaperTriangle)
  • FIX: Newly spawned Anchor Carts should attempt to force load chunks immediately instead of waiting for an entityEnteredChunk event.
  • FIX: Fixed localization issues with Track GUIs.
  • FIX: Disabling the Factory Module should no longer prevent you from cooking Abyssal and Quarried Stone.
  • FIX: Attempt to make Train objects survive linking and cart deaths (unlinking still needs work).
  • FIX: Anchor Cart should no longer request Chunkloader Tickets if the entity is dead.
  • FIX: Crowbar should no longer attempt to link dead carts.
  • FIX: Train Detector should no longer count dead carts as part of a Train. Issue #536
  • FIX: Crowbar Destruction Enchantment can no longer perform alchemy. Issue #519 (contribution by WoodStone)
  • FIX: Hide the Tank Valves Animation Tank from TankInfo calls. Issue #381
  • FIX: Properly Handle Invalid Regex Syntax in Routing Tables. Issue #518
  • FIX: Don't try to define Brick recipes if disabled. Issue #513

    • Boiler Changes:
Goal: Provide a more realistic interpretation of real life Boiler physics.
Steam Produced becomes a factor of Heat. Steam per cycle per tank = STEAM_PER_UNIT_WATER * (temp / maxTemp)
Fuel use less dependant on temp, higher temps need more fuel. Fuel used per cycle per tank = FUEL_PER_BOILER_CYCLE + FUEL_HEAT_INEFFICIENCY * (temp / maxTemp) + FUEL_PRESSURE_INEFFICIENCY * (maxTemp / 1000)
Differences between Low/High:
Max Temp (Low=500, High=1000)
Ticks Per Cycle (Low=16, High=8)
Efficiency bonus per tank remains similar.
Heatup times remain similar, but add/remove heat functions are smoothed out.
Heat Up: newTemp = oldTemp + (HEAT_STEP + (((maxTemp - temp) / maxTemp) * HEAT_STEP * 3) / numTanks
Cool Down: newTemp = oldTemp - (HEAT_STEP + ((temp / maxTemp) * HEAT_STEP * 3)) / numTanks

New Code:

Code as present in Version
		public double getFuelPerCycle(int numTanks) {
			double fuel = Steam.FUEL_PER_BOILER_CYCLE * efficiencyModifier * RailcraftConfig.fuelPerSteamMultiplier();
			fuel -= numTanks * Steam.FUEL_PER_BOILER_CYCLE * 0.0125 * RailcraftConfig.fuelPerSteamMultiplier();
			fuel += Steam.FUEL_HEAT_INEFFICIENCY * getHeatLevel();
			fuel += Steam.FUEL_PRESSURE_INEFFICIENCY * (getMaxHeat() / Steam.MAX_HEAT_HIGH);
			fuel *= numTanks;
			return fuel;
Code as present in Version
		public double getFuelPerCycle(int numTanks) {
			double fuel = Steam.FUEL_PER_BOILER_CYCLE;
			fuel -= numTanks * Steam.FUEL_PER_BOILER_CYCLE * 0.0125;
			fuel += Steam.FUEL_HEAT_INEFFICIENCY * getHeatLevel();
			fuel += Steam.FUEL_PRESSURE_INEFFICIENCY * (getMaxHeat() / Steam.MAX_HEAT_HIGH);
			fuel *= numTanks;
			fuel *= efficiencyModifier;
			fuel *= RailcraftConfig.fuelPerSteamMultiplier();
			return fuel;

Heat Adjustment Code (one of these two following functions are called once per tick):
		public void increaseHeat(int numTanks) {
			double max = getMaxHeat();
			if (heat == max)
			double step = getHeatStep();
			double change = step + (((max - heat) / max) * step * 3);
			change /= numTanks;
			heat += change;
			heat = Math.min(heat, max);

		public void reduceHeat(int numTanks) {
			if (heat == Steam.COLD_TEMP)
			double step = Steam.HEAT_STEP;
			double change = step + ((heat / getMaxHeat()) * step * 3);
			change /= numTanks;
			heat -= change;
			heat = Math.max(heat, Steam.COLD_TEMP);

Released on January 30, 2013 for Minecraft 1.4.7.

  • INFO: Updated to Forge (required).
  • INFO: Updated UniversalElectricity API.
  • INFO: Two new block ids were required for the Saltpeter Ore Spawner block and the new Walls.
  • NEW: Steam Locomotives!
  • NEW: Added Train version of the Lockdown Track.
  • NEW: Broke down and added a Creative Tab. *rages at Sengir for abandoning the faith*
  • NEW: Villager Detectors should now work with custom Villagers.
  • NEW: Added Locomotive Detector, put Wool in the Slots to represent colors.
  • NEW: Added custom death messages for the Tunnel Bore damage.
  • NEW: Added custom Walls: Sandy, Infernal, Concrete, Obsidian, Nether Brick, Brick, Stone Brick (all variants), Sandstone (all variants), Snow, and Ice.
  • NEW: Added Locomotive Track, will set a passing Locomotive's current mode. Whack it with a Crowbar to change modes.
  • NEW: Added Whistle Track, texture modeled after an Irish Whistle Post.
  • NEW: Added Iceman's Backpack, it can pick up and compress Snowballs into blocks and it can also be used to (re)supply you with a steady stream of Snowballs.
  • CHANGE: Steam Engines no longer explode when their energy bar fills up, instead they “blow a valve” and get stuck until someone whacks them with a wrench/crowbar.
  • CHANGE: Saltpeter world gen was completely rewritten.
  • Saltpeter now spawns in any hot and arid sandy biome.
  • It spawns one layer beneath the surface in large uncommon clusters (aka Caliche).
  • Saltpeter clusters will regenerate over time, provided there is still sand at the surface.
  • CHANGE: Saltpeter → Fertilizer recipe now requires 2 Dirt and 2 Sand.
  • CHANGE: Rebalanced Hobbyist Engines slightly, increase fuel usage per conversion from 6.4 to 8 and reduced the Steam/Water Tanks to 4 Bucket capacities.
  • CHANGE: Water Tanks have positive pressure.
  • CHANGE: High Speed Explosions are now more impressive and spread flames. I can do this because I'm fairly confident that I finally fixed all of the bugs with HS Track.
  • CHANGE: Ice/Snow Walls are now added to the Iceman's Backpack instead of the Builder's Backpack.
  • CHANGE: Engineer's Overalls now provide some protection from getting hit by a Locomotive.
  • CHANGE: Changed Infernal Brick recipe to be similar to Sandy Brick. Reduces the Soul Sand cost by a 1/5th.
  • FIX: Creosote Cells are actually registered now.
  • FIX: Completely scrapped the unreliable methods of detecting sudden stops at High Speed in favor of marking tracks as “safe” or “not safe”.
  • Safe tracks are HS straight tracks that are connected to other HS Tracks on both ends. This can include unswitched Turnout Switches, but Wye Switches are never “safe”.
  • Carts will explode if they are moving at HS and encounter a “not safe” track.
  • FIX: Fixed a bug in the collision code that could result in random HS Explosions of Trains immediately following a chunk load.
  • FIX: Link drag is only applied if the Locomotive Module is active.
  • FIX: Replaced all server side markBlockForUpdate() calls with a custom packet sender, should help reduce chunk updates that need to be sent.
  • FIX: Discovered and fixed a misconception related to explosion resistance that caused most blocks to have massively better resistance than intended.
  • FIX: The Trackman's Backpack will no longer pick up everything.
  • FIX: Liquid Loaders once again obey the Top Off mode.
  • LANG: Added Chinese Translation by crafteverywhere.
  • API: Added a new function (clearPairings()) to AbstractPair in order to fix a minor bug with the Tuning Aura.
  • API: The network changes required some changes to the Track API.
