On Track Lewisham runs relaxed, child-led train play sessions for autistic, ADHD and SEND children at Lochaber Hall in Lewisham. Using a huge collection of Tomy Trackmaster sets, children build the track, run the engines and take charge of the whole layout at their own pace. Sessions are designed around sensory and social needs, with no fixed programme and no pressure. Parents and carers are welcome to stay and join in or sit back. No formal diagnosis or referral needed.
