Must have been fairly late itself?
Departed Park Lane at about 1615 iirc, same time the E2 left (1557 departure).
I know the E1 was regulated that was due to leave around 1610, and apparently the two E1s prior to that were the same too.
Was it just the traffic on the bridge or was it other things too?
