"Brno Bus Peak Fleet.html" (project root) was built on 2026-09-29 and published as https://claude.ai/artifact/Q1cS9fRTKPNHJYbmsNPv3T. It covers the city bus lines 40–84, the express lines E50/E56/E75 and the replacement line x75. The vehicles are from Fri 25 Sep and the network is the one running from 29 Sep. The sheet is generated by pipeline/brno-bus, which imports helpers from pipeline/brno-trolleybus, and those import from pipeline/brno. See brno-trolleybus-peak-fleet and city-pipelines.

Non-obvious facts:

• In the IDS JMK GTFS, buses are route_type 3. The feed splits long workings at timing points such as Úzká, Královo Pole, nádraží and Haškova. scripts/propose.py chains trips and prints each leg's successors, which gives the order of legs on each line.
• bmhd.cz files lines under other numbers: 54 under 52, E50 under 50, 55 and E75 under 58, 46 and 66 under 57, 70 under 42, and E56 under "56". The 54, E50, 55, 66, 70 and E56 pairings are confirmed by the IDS PDFs, jrbrno.cz and bmhd.cz; 46 and E75 are inferred.
• Line 63 starts on 1 Oct 2026, so the service day is 29 Sep itself, not a later Friday.
• 48 and 74 are run by BDS-BUS (Pozořice). Their vehicle types come from the seznam-autobusu.cz pages linked in their records. The IDS JMK livery, the MAN Lion's City and the SOR CN 12 have only stand-in pak objects; I asked the pak session to add them.
• One-way peak lines have no timetable at the far end (Departure every 0). Through stops keep the real minute.
