THE DECISIONS

The reason, then the readback.

9 Apr 1950
RecoveryClaude Haiku 5.5
A depot repair becomes an ore train
Stated intent
Buy one ore train at the connected depot (84,224): Chaney 'Jubilee' locomotive (engine 8) with 3 Iron Ore Hoppers (wagon 35, 30 t each).
Reason at the time
The depot exit now reads compatible_track and connected, so a train can leave onto the line.Recorded excerpt · haiku decision seq231
Game action
Purchase a Jubilee locomotive and three ore hoppers.
Observed / reviewed result
The purchase returns 90t IORE capacity. Later fleet observations record deliveries by the original and cloned ore trains.
Canonical haiku references: #194, #195, #231, #232, #1691. Result wording is editorial interpretation of these records.
14 May 1951
Unfinished expansionClaude Haiku 5.5
The second line stops short of a service
Stated intent
Build the wood line between Gunfingfield Woods (station 6) and Slondingworth Heights (station 7), with budget set to the high quote.
Reason at the time
The quote is buildable at £3,643 to £5,201 over 64 tiles, and fits 3-tile trains.Recorded excerpt · haiku decision seq795
Game action
Build track between the forest and sawmill stations.
Observed / reviewed result
Track construction succeeds. No wood-service train is purchased before this controller stops. The stated plan mixes rail infrastructure with trucks.
Canonical haiku references: #795, #812. Result wording is editorial interpretation of these records.
1 Jan 1954
InvestigationGLM 5.3 Flash
A repair story meets a conflicting readback
Stated intent
Convert the shared-corridor junction block signals to path signals.
Reason at the time
#69 (grain) stalled 15 days at [87,204] behind block signal [88,204] while #42 loads inside the same block at station 9 — the block signal oversubscribes the shared steel/grain approach and serializes the two trains even though station 9 now has two platforms.Recorded excerpt · glm decision seq2220
Game action
Remove and rebuild two junction signals as path signals.
Observed / reviewed result
Both removal readbacks report the existing type as path. A block-to-path conversion is not established, and later waiting recurs.
Canonical glm references: #2220, #2221, #2223, #2692. Result wording is editorial interpretation of these records.
