Recently my sister and her husband were in Colombo and they came across this bus.
This passenger bus symbolizes the commissioning of the Cylon Transport Board (CTB) on the occassion of nationalization of private bus companies on Jan 01, 1958.
The then Prime Minister Hon. S. W. R. D. Bandarnaike and transport minister Hon. Maithripala Senanayake made the innaugural journey from Veyangoda to Colombo.
This Mercedes bus (60 seater) bus was made in Germany in the year 1957 and is in good running condition !!
