I can't think of a name for the Romford - Upminster single-track
line, although I'm tempted to go for The Only Way I suppose the Emerson
Park Shuttle would do, since the line is discussed so rarely it hardly
needs a snappy name. I'm not sure it will be on the tube map.

It is, because the tube map now goes out as far as Shenfield (and
Upminster obviously).
