宇通ZK6128HG1 Yutong ZK6128HG1
In 2012, a right-hand drive Yutong full-sized super low-floor single decker was observed in Zhengzhou Yutong Industrial Park, Zhengzhou, China. As the bus was painted with KMB standard champagne gold livery, most bus enthusiast believed that KMB would receive this demonstrator for testing. However, this bus finally was first appeared in Macau with Reolian livery in Sep ., 2013 and the model name ZK6128HG1 was first known to the public. As shown in the model name, this demonstrator is 12m in length. During the test run in Macau, the ZK6128HG1 demonstrator only received a temporary license T380 and fleet no. 3088, immediately behind the Yutong ZK6118HGE in Reolian. The KMB standard maroon colour seating was changed into red and black.
The trial in Macau initially not included putting the bus on revenue service, however, as request by different parties, this ZK6128HG1 finally serving on route 3 in early Nov ., 2013 though Reolian already declared bankrupt at that time. The demonstrator was returned to Yutong after the trial completed. When most of us did not remember the existence of this Yutong, another ZK6128HG1 decorated with champagne livery without the bronze band was delivered to KMB in Apr ., 2014.
This KMB demonstrator was with running light and Nippon Denso air conditioning unit which are different from the demonstrator tested by Reolian. This ZK6128HG1 is powered by Euro 5 Cummins ISL series engine with ZF Ecolife gearbox, a combination already seen on ADL Enviro 400. Flip dot display supplied by Hong Long was chosen instead of the orange colour LED display. The Yutong ZK6128HG1 is the first single decker in KMB with low floor area starting from the entrance to the rear part of the cabin.
KMB registered this Yutong ZK6128HG1 as TB4320 (fleet number AYT1) on 17 Nov ., 2014 and it is the second China made bus in the fleet. AYT1 serving on Norther New Territories route 70K along with other single and double decker since 15 Dec ., 2014 and then route 72A serving between Tai Wai Railway Station and Tai Po Industrial Estate since early Aug ., 2015.
Unfortunately, this sole Yutong single decker in the fleet was withdrawn on 15 Feb ., 2016 as a result of surplus of full-sized single decker in KMB fleet. Except 70K and 72A mentioned above, AYT1 also served route 49X, 73, 85X and 273 during it service life. To go one step further, the demonstrator evaluated in Macau were stored in the dealer in Hong Kong before sent back to Yutong.
