Starting Tuesday, the characters will appear on eight new routes including G21 (Rangsit-Rama V Pier); G59E (Min Buri-Si Phraya Pier via the expressway); R3 (Rama IX Park-National Stadium); and R41 (Tok Road-Happyland).

The other routes are Y59 (Taling Chan Train Station-Krathum Ban); Y61 (Settakij Village-Chatuchak Bus Terminal); B44 (Rama IX-Suttisarn) and B45 (Ua Arthon Beung Kum-Memorial Bridge).

“G” stands for green, “R” for red, “Y” for yellow and “B” for blue.

The B area covers inner suburbs of Greater Bangkok and some of its northern parts; G is for eastern and northeastern parts; R for southern and southeastern parts; and Y for southern and western parts.

“E” stands for expressways.

To ensure commuters do not get confused, the old route numbers are visible on the front of buses.
