Every day I drive past this old railway which I never saw in action
but have often heard about:

...but the map of 1932 doesn't show the original track to Long Grove.

The original route is shown in "Epsom's Hospital Railway" by R. I. Essen
(1991) - I got my copy from Pullinger's (who published it) in Epsom High
Street. I don't think they are still there, but other local bookshops
might have it, and I expect Epsom library will have a copy.

Does anyone know exactly where it went and if there are any traces?

The route skirted the grounds of St Ebba's (i.e. south of the later
Horton Light Railway), crossed Hook Road just north of its junction with
Horton lane, then it turned sharply SW in order to skirt the NW edge of
Great Wood and then finally enter the Long Grove site.

It ought to be visible from the air:

I can't see any obvious remains. The area has been ploughed up and parts
re-developed many times since 1907. And remember that the original was
only a contractor's railway which would have been lightly laid with no
substantial earthworks.

‘Puffing Billy' ran down and killed 64-year -old Mary Tobin at the
Hook Road crossing...

...but where was that crossing?

I would say about he
