The Leyland Titan PD1 with ECW body was favoured by some operators within the Tilling's Group during the late 1940's and 50's, the vehicles were a common sight in their red or green group liveries.

The ECW Leyland PD1 was one of OOC's launch models, the casting is also the basis for the Bristol K ECW bus (407).
Only four releases have however been made since 1995 with the last appearing back in September 1996.
