RCT2 Coaster Designs

52,927 roller coaster layouts made by players for RollerCoaster Tycoon 2 / OpenRCT2, each one a closed circuit that can be built piece by piece in the game, and each one rated by the game itself (excitement, intensity, nausea, speed, length, drops, air time, cost).

They come from 20+ years of community track designs, saved games, scenarios and parks, and cover 31 coaster types.

Every row has its layout as a sequence of track piece tokens, and a ready-to-play .td6 track design file: drop it into OpenRCT2's track folder and build it.

from datasets import load_dataset

human = load_dataset("ggmolly/rct2-coaster-designs", split="train")
row = human[0]
print(row["ride"], row["excitement"], row["tokens"][:8])

# Play it: OpenRCT2 lists it in the ride's track designs.
open(f"{row['id']}.td6", "wb").write(row["td6"])

Columns

ride_type	int	RCT2 ride type id
tokens	list[string]	The layout, one token per track piece (see below)
num_pieces	int	Number of pieces (≤ 1,024)
excitement, intensity, nausea	float	The game's ratings
max_speed_mph	int	Maximum speed (mph)
ride_length_m	int	Track length (metres)
drops	int	Number of drops
air_time_s	float	Total air time (seconds)
cost	float	Construction cost of the track, in the game's money
td6	binary	The TD6 track design file the game rated
sources	list[struct]	Every file the design was found in (collection, url, file, license, redistribution)

Splits: train 47,669, validation 2,637, test 2,621.

Tokens

A token is an OpenRCT2 track element name (TrackElemType, e.g. flatToUp25, leftQuarterTurn3Tiles, rightVerticalLoop), optionally followed by:

• |inv: the piece is built with the ride's inverted track (flying, lay-down and multi-dimension coasters). Its roll swaps between upright and upside down.
• |lift: the piece carries a chain lift.

A layout starts with its first station piece (beginStation, then middleStations and endStation; a lone endStation is a one-tile station), facing direction 0. It follows the track in its direction of travel and ends on the piece that leads back into that station. There are 393 distinct tokens. Diagonal track is included.

Every layout obeys the rules the game enforces when a player builds track by hand, so it can be rebuilt piece by piece in a live game:

• The pieces are ones the ride's construction window offers without cheats, with chain lifts only where it allows them.
• The track never passes through itself.
• It never goes below its station or above the ride's support limit.
• Pitch and roll always connect.
• There are at most 4 stations, none touching another, each with room for an entrance and exit.
• At most one on-ride photo section and one cable lift.
• No piece starts where another one ends, except at the station, so the game always follows the circuit unambiguously.

How the ratings were made

Each layout was exported as a TD6 file with its ride's most common standard vehicle and train length (from the designs themselves). OpenRCT2 (v0.5.5-122-ge9fedc198f, with a small headless trackinfo command) placed it on a flat map, built its stations' entrances and exits, ran the ride test and printed the results. Only designs the game rated are included. Layouts that stalled, failed to start or were refused were dropped.

The ratings therefore describe the bare track with a standard train. They ignore the original scenery, theming, vehicles and operating settings, so they differ from what the design scored in its own park.

Designs have a median of 108 pieces (up to 1,023) and a median excitement of 5.75.

How they were collected. The designs come from a dataset of about 297,000 attractions extracted from .td4, .td6, .sv4, .sv6, .sc6 and .park files. RCT1 designs were converted to the RCT2 ride with the same track, as OpenRCT2 does when importing them, and so were OpenRCT2's RCT1-style types (hypercoaster as corkscrew, classic wooden as wooden, ...). A design is kept once per ride type, however many files contain it. Most rows are left out:

• 89k are not roller coasters.
• 35k are split into several pieces of track, and 13k don't close their circuit.
• 47k break the hand-building rules above. Most of these go underground or above the support limit, or use cheats (pieces or chain lifts the ride doesn't offer).
• 7k are coasters with no RCT2 vehicle that a TD6 file could store: single rail, hybrid, alpine, LSM launched and spinning wild mouse.
• Shuttle coasters (reverse freefall, inverted impulse) never close a circuit, so none remain.

Sources and licensing

These designs are the work of the RollerCoaster Tycoon community, and their creators keep the rights to them. Most of them come from community archives and fan sites that publish no license. They are shared here as a research and preservation dataset of track layouts and game statistics: a re-encoding of each layout without its scenery, names or park. Each row's sources column says where its design was found, along with that source's license.

A design found in several places counts once per collection.

If one of these designs is yours and you want it removed, open a discussion on this repository with its id (or the file name in sources), and it will be taken out.
