The Yutong ZK6126HGA is a Euro 6 single decker city bus produced by Yutong. Private operators in Singapore operate this bus, with this one operated by Tong Tar Transport. Unlike the Yutong E12s, this Yutong is powered by a Euro 6 Diesel engine.
Update: in 2022, this particular bus, along with PC9851X, served briefly on RWS8 before being bought by Woodlands Transport.
