First Capital Connect - Another fine mess !

In the words of Stan and Ollie "That's another fine mess you've got me into". This afternoon I thought I'd see how the Thameslink trains were running back to Mill Hill from City Thameslink. "No Service" was the answer? What, none at all. Further investigation showed that the station was shut. I made a few enquiries. Apparently an unfortunate lady commuter had slipped over on the platform this morning. Although this was terrible, why did the station need to be closed all day? You'll love this. Word on the street is that the platforms were treated with a new "anti slip surface". What happened next? It became slippery when it was became wet. The health and safety advisors deemed it "unsafe" and shut the station. Could you make it up?
