RailLogic made a major jump from route-catalog construction into a more complete passenger operating model. Recent work unified service timing, fare calculation, multi-train pathfinding, transfer presentation, and route auditing while the rail product name was finalized as RailLogic.
- Standardized the commercial maximum service speed at 311 mph (500 km/h) and added acceleration / cruise / deceleration timing so short segments no longer assume instant travel at maximum speed.
- Locked mileage-based passenger fares at $0.19 per mile for Regional, $0.22 per mile for Direct, and $0.25 per mile for National Hub Nonstop, with mixed-service trips priced from the actual mileage and service type of each leg rather than a transfer surcharge.
- Added unlimited multi-transfer rail pathfinding that can combine Regional, Direct, and National Nonstop services, uses real scheduled TrainRuns, respects minimum connection windows, handles time zones, and ranks viable itineraries by arrival time and transfer count.
- Improved connection ranking so repeated schedule choices on the same route combination are reduced to the best useful options instead of flooding the passenger with near-duplicate itineraries.
- Reworked the reservation presentation into a wide planning column and a continuous right-side timetable showing Station, Arrival, Departure, and Service / Action, with BOARD, TRANSFER, and EXIT behavior kept inside one readable journey table.
- Refined connection cards so each itinerary clearly exposes fare, departure / arrival timing, total duration, transfer count, service mix, and transfer cities before the passenger selects a departure.
- Expanded Southwest Direct service data, corrected time-zone and rail-node behavior, and continued aligning the reservation screen with the same service and schedule model used by the route catalog.
- Added the Western Intermountain Regional passenger service from Phoenix to Salt Lake City, serving Camp Verde, Flagstaff, Kingman, Henderson, Las Vegas, St. George, Cedar City, and Provo before reaching Salt Lake City.
- Audited and validated Phoenix ↔ Salt Lake City National Nonstop service at 828 miles and Phoenix ↔ Seattle National Nonstop service at 1,679 miles in both directions, including fares, elapsed time, daily departures, average speed, and time-zone behavior. The Phoenix ↔ Salt Lake City Direct overlay was also validated in both directions.
- Locked a new network-design rule for the Regional audit: a Regional service should normally connect meaningful major terminals, Direct stations, National Hubs, or inter-regional gateways along the same physical corridor rather than terminate at an arbitrary Regional station.
- Established a common national timetable pattern for implementation across all six regions: Nonstop → Direct → Regional → Direct → Regional → Direct → Nonstop between the four-hour National Nonstop anchors. This operating pattern is a planning standard and will be wired into the timetable generator next.
Result: RailLogic now behaves much more like an integrated passenger railway model rather than separate route, booking, and timetable demonstrations. Physical corridors, passenger services, real departures, fares, transfers, and the reservation UI are converging on one operating system.
Next: implement the national departure pattern in the timetable generator, continue the Southwest audit through Regional and Direct endpoint structure, rework corridors such as the Rio Grande Regional where an ordinary station currently acts as an artificial terminus, and keep validating every service in both directions before locking it.
