Whatt??? A northerly runway on a 02/20 direction? You guys have no clue, do you?
SIN/WSSS has 2 runways, 02L/02C and 20R/20C. The center RWY is the one on the eastern side, towards the military side. The third RWY (02R/20L) belongs to Changi AFB of the RSAF. It's the most easterly runway, with no (official) TWY connected to SIN.
SQ777 and AWR are wrong, gb777 and Max Tow (partly) are correct.
