This is one of many Tram Tunnels in the area (Visiting another later so will be another report) They were used by the cement company to move chalk on trains to the cement works were they would then use that chalk to make cement this Tunnel I believe has never had A report before and not that many people know about it as many people know about the Northfleet ones there is currently no graffiti in the tunnel (I hope it stays that way) Apparently soon there going to open the tunnels up as A nature walk but as its (Bellways) there probaly going to destroy them Not much to show but still an amazing tunnel Enjoy
