I'm glade you think so but I never said that.There is no such thing as a perfect solution. One of the drawbacks of battery trains is how often you have to replace the batteries and the cost. The distance it can travel without a full recharge is also an issue as well as how long it takes to recharge the train although a ReBaar type system would go a long way to relieving that.OK now we have battery on top of hydrail and catenary
As far as this idea that some of you have of battery trains being revolutionary, you need to get out more. Battery trains have been around for a century...…………….there is absolutely, positively nothing revolutionary or even novel about them. Battery trains are the same as they have always been and have proven themselves to be efficient and safe. The ONLY difference between older battery ones and the new ones is that the batteries have improved immensely. This means that now they are actually more useful for true commuter/suburban needs.
Most systems , like the new ones built by Bombardier, Stadler, and coming soon Siemens, are dual-mode...…......they can run on both catenary and battery alone. The Auckland system is opening this year, Stadler just got a contract last month for 55 FLIRT battery trains for Germany, Austria is opening several battery lines this year, Britain has already started testing it's new battery trains on regular track for deployment in Anglia, and Ireland's DART announced last month that it is buying 600 carriages to battery and catenary trains to replace the diesels they run now.
