I do have a tiny bit of unverified info, that there was once a track running behind Neil Road, more of a track to ferry goods on the rail
(from Tanjong Pagar station to storage areas). However the tracks are no longer there. And Neil Road was rather near to Chinatown
as well, unless you have a specific location you would want to pinpoint.
Back in the early 1900s', apart from what we now know as the KTM railway tracks between Woodlands and Bukit Timah, the original line as planned by the British used to continue towards present day Newton Circus before passing through stations along Orchard Road/Somerset Road, Clemenceau Avenue, New Bridge Road, Tanjong Pagar Road, Cantonment Road, Telok Blangah Road and finally terminating somewhere near Pasir Panjang container terminal.
This was years before the network of railway lines was transferred over to Federated Malay States Railways (FMSR), predecessor of Keretapi Tanah Melayu (KTM).
