A little bit of history
Except for the solitary 33 ft Atlantean (900), Lothian had standardised on 30 ft double deckers until it came to place its first substantial order for the Atlantean’s successor, the Olympian.
From then on, the longer chassis was to be the norm, obvious in the short window in the middle of the body. They broke with tradition of over 25 years in being bodied by ECW of Lowestoft instead of by Alexander of Falkirk and were the first high capacity double deckers.
127 ECWs were to be bought in three batches, 777 being one of the third batch, spending all its days at Marine garage from where it often operated on service 26. One further identical bus ran briefly for Lothian before being bought back by Leyland and used as a demonstrator overseas.
