This is actually part of the the Bukit Timah Railway Station.
Its just before the Old Ford Factory and Firestation. There is even some sort of a shopping centre next to it called the RailMall.
Havent really fixed on the date but again it will be a small group. We wont be exploring the whole route but part of the railway. Should be a few hours event but expect to do some trail walking.
I will post up more details later on...interested parties please post here with your questions.
