 | | Golders Green depot is east of the station; it can be entered at the south end from the tubes, or from the station by reversing in a siding extending a short way into the tube. |
 | | The success of the CandSLR led to a number of new tubes being proposed; six of these were built and opened between 1898 and 1907 (see the Bakerloo, Central, Piccadilly, and Waterloo and City Lines for those not discussed here). |
 | | The tube was 3.1m (10'2") in diameter in the northern section, and 3.2m (10'6") in the straighter southern section, to allow for the extra sway of the faster trains; some later sections were 3.51m (11'6") in diameter to provide better ventilation. |
