For Camden Road Station ( Overground ), it's easy on the northbound 46 because it stops just beyond an obvious railway bridge.
Southbound there is also a bridge, but not at the station.
In the end, fbb chickened and compromised by showing he 46 as "ideal" for Camden Road and the 24 and 168 as serving Camden Town. He added a dotted line (later with stick man) to show that the distance between them was easily "walkable".
But now it's shiny new overground ...
An additional investment in extra capacity is being proposed because Overground passenger figures are rising sharply and are projected to increase by another 25 per cent within a decade. TfL says passenger numbers have risen from 33 million** a year on the former Silverlink Metro network to 88 million now. The TfL Business Plan envisages the lengthening of all 57 Class 378 units to five cars from the December 2014 timetable. There may also be up to five additional trains, which would again be of five cars.
fbb will present his and Diane's version of the finished "spider" tomorrow.
** Figures for the pre-privarisation super seedy days are not easily available.
