Text Appearing Before Image:
the new underground station at Charing Cross (Embankment), which forms such a convenient junction for the Underground Railway, the Charing Cross, Highgate and Hampstead Tube, and the Bakerloo Tube. Whereas, until recently, it was necessary to leave the Underground station and make a detour through the streets to reach either of the two tubes, one can now enter them direct by means of the series of moving stairways. A few words may be said as to the lighting of this station, illustrated by two photographs taken by the kind permission of the Underground Railway Co. Fig. 1 shows the method of lighting the platform of the Charing Cross and Hampstead Tube terminus. This is lighted by metal filament lamps in Superlux globes and Benjamin rings, the units being spaced at intervals of about 25 feet. A test showed that an illumination on the platform from 0*8—1*2 ft candles were provided between the units - a figure considerably above the 0*25 ft candles suggested as the minimum for main station platforms. The second photograph (Fig. 2) shows the entrance to one of the moving stair-ways. The lighting of this staircase is decidedly good, the lamps are screened by plates across the ceiling so as to be invisible to the descending passengers.
Text Appearing After Image:
The photo-graph gives a very good idea of the soft and restful conditions. The space adjacent to the entrance to the stairway is also illuminated by 100-watt metal filament lamps in Superlux globes. For some of the information used in this article we are indebted to the courtesy of the General Electric Co., Ltd. THE LIGHTING OF SQUASH RACKET COURTS. Some time ago we referred to the lighting of Squash Racket Courts*—quite an interesting problem for the illuminating engineer. There has recently been a boom in covered courts of this kind. The essential point in this, as in most other ball games, is to avoid any inconvenience due to glare, and to keep the lights as far as possible out of the direct range of vision.
