‘The PuzzleLine’ is our free adventure trail at stations along the Darent Valley rail line.
The challenge involves completing a secret mission at each station from Swanley to Sevenoaks. To complete the missions, you answer questions and solve puzzle designed to test your skills and knowledge as a secret agent.
While the questions are fun, some require a superior level of puzzle-solving. Others simply require a keen eye. Help with the answers is available on the PuzzleLine website.
The PuzzleLine can be completed in one or several visits to the stations. The trail is suitable for anyone aged 11 and above.
PuzzleLine leaflets will be available from stations along the Darent Valley rail line and selected nearby retailers.
Answers are submitted on the PuzzleLine website.
Everyone who completes the trail can download a completion certificate and enter a free prize draw to win one of three escape room games at TimeQuest Escape Rooms. The prize draw is open until 31 August 2025. Competition terms and conditions apply.
We worked with award-winning escape-room company TimeQuest and the Darent Valley Community Rail Partnership to develop the trail.
