After about half an hour of hanging around Olympia we eventually went to
Waterloo. The train did not have to reverse en route.

You would have definitely reversed at Kensington Olympia. There is no other
way back to Waterloo.

The route that would have been taken from Brixton would have involved
diverging left across Factory Junction, at Wandsworth Road, rather than
continuing over Stewarts Lane flyover, then dropping under the Victoria and
Waterloo lines to gain the northbound West London line at Latchmere
Junctions, then continuing to Olympia. From Olympia the train would have
reversed to Latchmere No. 3 Junction before taking the curve to join the
South Western main line to Waterloo at West London Junction, rejoining the
normal route just after the Stewarts Lane flyover trails in.
