I found myself thinking, "why start at Shenfield?"

Is there so much demand on that line for such a route, or capacity further
up it (at Chelmsford for example)?

Shenfield is where the line stops being 4-track and splits into two
2-track lines (one to Southend the other to Chelmsford and beyond). As
well as being a junction, it's always been an important railhead and
interchange point. And the "town on the edge of London" although being a
couple of miles inside Essex.

Also the railway through Chelmsford, and the station itself, is on a brick
viaduct, which makes any additional trackwork required to turn back a
large number of trains somewhat impractical.

Well, yes, but the capacity from Southend and the Chelmsford direction is
(as you say) throttled and I'm wondering why the people beyond Shenfield are
suddenly going to get a great urge to travel to Maidenhead and beyond and,
if they do, whether those outer reaches are going to be able to handle such
a demand.
