I'm not totally sure where the lift connected to, but I gather it was
to the main line

Yes - more precisely, it was to the carriage sidings just north of the
Windsor lines, roughly where the taxi road to the Eurostar terminal is
now. There was originally also a second, smaller lift to take coal
wagons down to the W&C power station.

and the Bakerloo line,

No, as John wrote, there was never a Bakerloo connection. The W&C runs
below and just beyond the gate line at Waterloo, with the depot at the
east end of Lower Marsh. Then comes the Northern, further west, roughly
mid-way along most platforms. The Bakerloo is further west still, pretty
much at the country end of platforms 1-3 and so at the far easterly end
of Lower Marsh. (It then follows Westminster Bridge Road to cross the
Northern at Lambeth North.)


Although, for interest, you can see Bakerloo trains popping into the
open nearby at the corner of St Georges Road and Lambeth Road (the
"London Road" depot). If you can stand on something to see over the
wall.
