Dave checks out the world's first solar powered battery storage train!
The Byron Bay Solar Train.
NOTE: This is a neat tourist attraction, but it's NOT a magic "green" solution to train travel.

A Byron Bay company have converted an old 1950's "red rattler" Sydney train into a battery storage solar powered train.
Solar panels on the train roof can charge the train batteries which can last for an entire days service. a 30kW solar system on the train station roof provides fast charge power and power back into the grid when not being used.
