There is also another possibility, a VO2x due to be exported to
UK operator.
*Correction. To make my point clearer.
A VO2x from other depot doing modification works in Hougang
depot prior for its UK delivery since Hougang depot is a bus
assembly plant. Don't look like a Hong Kong Olympian to me, be
it from Long Win or CityBus.
But this is still just a possibility.
