Task
To provide optimised clearance diagrams for the meter gauge sections in Stern & Hafferl’s branch-line and tramway systems.
Solution
- Examination of the existing fleet vehicles to determine their construction gauges, based on the different types of track superstructure
- Calculation base for construction gauges: “Ordinance on the Construction and Operation of Street Railways” (BOStrab), guidelines from December 1996 (“Dimensioning Track Clearance“)
- Definition of new and optimised construction gauges for all 12 types of vehicles
Outcome
Clearance diagrams were provided for the different rail systems; we have also outlined additional travelway space (e.g., hazardous and safe areas, room for operation) as well as safety margins that need to be taken into consideration in order to fully comply with various regulations (EisBAV / StrabVO).
