What do you mean by "through services from the GW suburban stations"?

The H&C line stations were originally part of the GW, with connections
to the West London Railway, together with the crossovers at Paddington
allowing through working (reputedly even a Windsor to Aldgate service at
one time!). In latter years the only through working tended to be by
freight services, until the crossovers became redundant and were removed
in 1968.

Through passenger trains changed from steam to Metropolitan electric locos
(eg Sarah Siddons and her sisters) at Paddington Suburban (Bishops Road).
Freight trains were steam hauled throughout. It was great watching the
surprised look on the faces of waiting passengers as a pannier tank on a
freight train came rumbling through the Circle line stations.
