Best Headway
A browser-based railway headway and capacity simulator for testing routes, rolling stock, signalling, timetables, and train spacing.
Field notes
The site lays out a seven-stage pipeline from track layout and rolling-stock data through scenario construction, tick-based simulation, interlocking checks, and diagrammed results. Its engine description divides automatic train operation into brake, cruise, and acceleration zones, while the capabilities section cites configurable time steps, editable tables, live validation, and occupancy checks. The homepage says the tool runs client-side without an account, although no interactive scenario or sample diagram is exposed in the supplied page evidence.
