This photo challenge, was announced as per usual on the Happening London Instagram feed and pooled with past challenges in the London Photographers Community.
We asked people to share a London Tube photo of theirs with the challenge hashtag: #HLtube.
We didn't get many submissions; special shout out to those who made the effort. Hope more of you will take part in future challenges, which will also be announced on the Happening London Instagram feed.
Top submissions for HLtubeTrain parked at Finsbury Park.
