In 1994, The Two started off as Double 2, with buses running every 15 minutes.
The yellow numeral 2 was replaced with a red numeral 2 with a yellow outline and a die on it.
Double 2 now goes yellow as of 2004, introducing a new Rainbow route, Rainbow 2. The frequency of every 12 minutes replaced the 15 minute frequency and introduced the low floor buses.
Rainbow 2 got a major makeover with: a new name, air con, leather seats and laminated floor. The frequency remained the same and it became The Two.
As of October 25, 2015, The Two gets bigger buses, with: more seats, fast 4G wifi, USB sockets, audio stop announcements and a new frequency of every 10 minutes, instead of 12 to improve reliability.
