A little bit of history
In the years immediately following the deregulation of bus services, operators were very wary of making substantial investment in new buses and it was a lean time for the bus builders.
Then in 1988, Lothian placed an order for 36 Olympians which marked a return to Alexander bodies. With Cummins engines and ZF gearboxes, they broke with a tradition of buying Leyland engines which stretched back to the early 1950s but these were to be the first of a highly successful design, followed by several more batches of broadly similar buses, some having very long service lives.
The first ten of these buses were regularly used on service 26 before conversion to open toppers for the tours fleet. In due course 322 became a driver training bus but was restored to the heritage fleet.
