Something you don’t see on a modern rail systems are old fashioned concrete mileposts, but I stumbled upon one on the northbound platform at Mong Kok East station.
And another south of Fo Tan station.
Called 里程碑 in Cantonese, over on the HKiTalk.net forums I found a thread discussing mileposts on the East Rail Line:
The East Rail line is approximately 34 kilometres in length, with mileposts found every 500 metres.
Distances are measured from Hung Hom Station.
Located to the left hand side of the track, headed northbound, existing concrete mileposts include:
- 2.5 (Mong Kok East)
- 4.5 (Kowloon Tong)
- 12 (Fo Tan)
- 14.5 (University)
- 18.6 (Tunnels No. 5 and 5A)
- 21 (Tai Po Market)
- 28.5 (Fanling)
- 30 (Sheung Shui)
They also detailed how chainage is displayed along the former KCR system:
Example – A18+598 at tunnel No. 5A:
18 kilometres + 598 metres from Hung Hom.
The letter indicates:
- A = Mainline
- B = Racecourse branch
- S = Siding
- L = Lok Ma Chau Spur Line
- M = Ma On Shan Line
The lowered marked chainage is A0+030 at Hung Hom.
The highest marked chainage is L37+471 at Lok Ma Chau Station, and A33+579 at the Shenzhen home signal.
