- Based on Single Slip Coaching, but focus on maximum capacity
- 700 m trainset is divided into two sections shorter than 400 m, stopping side by side in larger stations
- After leaving the station both trains couple again virtually to one 700 m trainset
Operation
- Slip coaching procedure, which is based on Single Slip Coaching, but with focus on maximum capacity (same procedure at intermediate stations)
- Train consist of main train section and smaller sections with 4 coaches each
- If the trainset should stop at a station with 400 m long platforms in its entirety, it has to be separated into two sections
- Before reaching the station, the rear section begins to slow down while remaining virtually coupled as long as the trains are within braking distance
- The rear section has to brake as if the switch in front of the station was a red signal to allow it to turn after the first section has passed it
- Both sections stop at the station side-by-side
- The former rear section departs first to now run at the front of the combined train
- The front section stays at a lower speed until the rear section approaches within braking distance, a virtual coupling process is started and the sections accelerate to maximum speed
Chances
Remarkable capacity increase without additional infrastructure
- Track capacity and capacity of railroad nodes can be increased by using Double Slip Coaching
- Remarkable capacity increase without additional infrastructure
- Trains can run with double length, although the platform length remains the same
- Case study: more than tripled passenger capacity per hour on the existing infrastructure
- Double Slip Coaching technology enables to run 700 m long trainsets in passenger transport
