As the Railways continued to operate during the hours of darkness lamps were needed for a multitude of functions. Most Handlamps contain glass lenses of Red and blue/green and sometimes orange with either no glass or a clear one for use as a torch. Thus they are called three aspect and four aspect lamps with the centre section revolving to show the different colours. There were Lamp Rooms where the lamps were filled with kerosene, the wicks trimmed and any repairs made.
No one would have ever imagined in that era that these railway signals can set up the trend for home decor by replacing that old fashioned lantern.
