Kwai Fong Station is among one of the older stations on the MTR Network, and it's also one of the…read morefew where the MTR operates on elevated tracks. That being said, this station unlike most of the others is not air conditioned. On the contrary, that's not too much of a problem since this station is serviced by the Tsuen Wan Line, so trains tend to come every 2 minutes.
Over the several decades that this station has been in service, ridership numbers have grown drastically as the area around the station boomed into a densely populated residential and commercial area as well as a major transit interchange offering bus services to new territories districts like Tin Shui Wai, Tsing Yi, Tsuen Wan, and by bus transfers, Yuen Long and Tuen Mun.
As a result, this station is often very busy, and having to line up very briefly to use the fare gates can be a regular occurrence. While a lot of people do board and exit the train at this station, you will more often than not be able to board the first train that arrives since the surrounding districts around Kwai Fong tend to prefer buses over the MTR, unlike the rest of the areas that this line serves.
Being the transit cheapskate I am, I try to find the best possible deal for commuting, and I'm sad to say this station is not served by any $2 discount octopus card fare savers. Being someone who works in Kwai Fong but lives in Hong Kong, I went with the City Saver Card offered by the MTR, which has greatly lowered my commute costs. It can admittedly be a bit awkward to use since I'd have to find a turnstile that has a ticket slot to scan the ticket on exit, which occasionally means I get shoved by an impatient commuter standing behind me, but that definitely made my trip on the MTR much more affordable.
