The way ahead at T5

Looks good. DLR tried it but had to put driver/guard into operation at the sharp corners e.g. Canary Wharf approach corner
T5 should be okay as they are tiny pods. The way ahead.

“…A world’s first in modern transit technology, the Heathrow pod system is expected to carry 500,000 people every year on the five-minute journey between Terminal 5 and the car park….

…A total of 21 Personal Rapid Transport (PRT) pods which use 70% less energy than a car will circulate around a 3.8km congestion-free track.

The vehicles can reach a top speed of 25mph and will eliminate the need for 50,000 yearly bus journeys around the airport…”

Incidentally Jubilee Line has a perspex shield between platform and train on some stations – great as the doors open in complete synchrony. Excellent safety enhancement to avoid human tragedies.
