Larger boxes generally adopted larger window panes (as seen here in the end wall by the staircase) although smaller boxes retained the divided panes - an example of which is illustrated at Upper Portland Sidings. The window arrangement along the front of the box should be disregarded as these were LMS replacements following bomb damage during World War 2. From 1906, another style of window pane was introduced, an example of which can be seen at Ilkley. The abnormally shallow staircase is a typical Midland feature, too, although this is not so obvious on lower cabins. |

On the block shelf, in shadow, are four sets of Midland Railway Rotary Interlocking Block instruments controlling the Fast and Local lines. To the left are the goods line instruments (described below). Out of view, to the right, was another permissive block instrument for the Second Up Goods line, whilst above the photographer, mounted on a roof-beam, was the "Overland Bell" which was rung from Hendon or Brent Junction No.1 to all boxes southwards as far as Finchley Road to assist in the regulation of Up Fast line trains. Incidentally, the box never fully recovered from its wartime damage, and when "mopping-out" the water always flowed to one corner! |

The pegging latch can just be seen on the right hand instrument - this required a knack to operate with one hand (whilst ringing the bell with the other) and was not as simple to operate as the similar instruments on the Great Central or Great Northern. The apparent pegging handle on the left-hand instrument is a dummy - at one time it would have allowed deflection of the needle for routing descriptions, but these were disabled in LMS days when routing bell signals were introduced. The original brass plate below the instruments could do with a bit of Brasso, methinks! |

The Midland Railway's idea of signalling a permissive Goods Line entailed the use of a block bell and nothing else, but after an unfortunate incident further down the line at Sharnbrook in the 1950's, all Goods Lines were equipped with proper instruments. As the BR standard block had not at that stage been introduced, LNWR instruments were used at all locations. The circular commutator can be rotated almost through 360° to show up to 6 trains in section; the plunger on the right side of the instrument has to be operated for each train. |

Notice also the vacant space and fittings for the West End Sidings Distant, removed in 1968. The background of this view would be marred today by the massive structure of West Hampstead power box, which controls the line from St Pancras right through to beyond Bedford. |
