Took MRT today and while waiting for train at Yishun, I notice
that the yellow flooring is still the same as before,
apparently there isn't much of progress...
Did some research and found some design for the platform safety
gate which might be or near to the design for the Singapore PSD at
elevated stations.

Top: Hong Kong Sunny Bay MTR ( most likely the design for
Singapore )

Top: Paris (uncertain)

Top: some imaginary PSDs somewhere is EWL

Top: HK Disneyland Line PSD, a little short in term of
height...

PS: I think I saw some glass doors being delieved to YIS. Can't
confirm though but the SMRT staff are also carrying them.
