Coal-burning steam locomotives. Originally these were fitted with condensing equipment to recycle the steam (rather than allowing it to escape into the tunnels), but the condensers made the engines very inefficient and they were soon removed. As might be expected, the air quality in the tunnels was not good, even though there were openings in the tunnel roofs at stations and elsewhere.
