Very good point. There’s also a potential for future upgrades. They may invest into catenary lines at some point, get rid of batteries and increase capacity inside vehicles. Or, switch to hot-swap batteries and increase vehicle turnaround and frequency. Or, they can switch to traditional concrete reinforcement for rails for future lines if they decide that the rails-on-slabs approach doesn’t work out as well as they hoped for. Their vehicles while custom-built are running on top of standard tram lanes, so they will be able to use traditional tram tracks, too.

VLRT seems gimmicky at first but the more I look at it the more sense it makes.
