Yesterday evening I caught a train from Billingshurst to Christs Hospital. When I got off at Christs Hospital, there was little lighting around and I couldn't see the way out. I was looking for access to the Downs Link which I was planning to use to cycle the short distance home. I walked down the platform a few meters and came across a rough gate and I wondered if that would give me access to the bridleway so I went through it. I emerged in what looked like an open area in the woodland which may have been formerly part of the station but I'm not sure, it was very dark and I had very limited vision of my surroundings. Not seeing any route to the bridleway I retraced my steps and decided to cross to the other platform and found the proper way out. What was the first gate I went through and could I have accessed the Downs Link from there? I don't think I should have gone through it as when I came back I saw a smashed sign on the ground that showed part of the word "Private".
