5-car O/P stock trains were run on the East London for a time in the
1970s. The cars were only 51' 1 1/4" (15.58m) long though, so I suppose
that is shorter than 4 x 20m cars.

As Recliner says, Canada Water wasn't around then - and nor were the
stations on the 'new' stretch of the line from Shoreditch High Street
up to Dalston Junction.
