An interesting little video on the BBC website, as we come up to the 70th anniversary of the Hiroshima atom bomb….

One of the few remaining trams which survived the Hiroshima bomb has been restored to commemorate the 70th anniversary of the attack.

It has been repainted its original colours – blue and grey – and has video testimony from survivors on board.

After the blast, the city’s tram system was back up and running in only three days.
