Default Thompson L1 fitting

If you look at the front of this Thompson L1 you will see that the lamp brackets have what looks like a lamp built into them. In this picture there are two of them in the centre but the near one is missing the cover.

Does anyone know what they are? The Hornby model incorporates them as well so they seem to be a particular feature of this locomotive and obviously serve a purpose. The odd thing is that the one at the top of the smokebox is not incorporated into the lamp bracket.

Wild guess, are they covers to dim the lamps as may have been used in wartime? R-

I thought they were electric lamps.

Quote from a web site "67731 to 67765 were all fitted with electric lighting".

So the oil lamp bracket would be just a back up in case the electric lamp failed? That would make sense and I suspect you are correct.

In that case I cannot fathom out why in the centre there are two electric lamps but only a bracket for a single oil lamp?

Probably easier to slot on an oil lamp than change a bulb. Take a look at Tornado. Has electric lamps with extended brackets for oil lamps.

Many Southern Region locos had electric lights in a similar fashion.

The Southern Region used head code discs to display the route, but these only work during daylight hours, so when darkness fell the electric lights were used on the engines that had them. Other locos had lamps instead. There are not many photos of engines with lamps on the SR because they only had them at night when photography was a bit more difficult!

The Eastern Region also used discs that were replaced at night with lamps.

There are dozens of pictures of Southern locos with lamps RFS. They are electric lamps. The discs were fitted above them in some cases.

Example below.

There was only ever one oil lamp on a lamp iron. It looks to me as if the right centre lamp is damaged so they stuck a new one next to it.

Edit. Looking at some pictures they do appear to have two electric lamps on the centre position. Strange. Like I said they only used one oil lamp.

From all the pictures I have collected that would seem to be the normal arrangement of two electric lamps with one lamp bracket on them. Even the Hornby model copies this arrangement.

Maybe the extra centre lamp is a red one for when needed.
