Mystery "BU" signal on Cambrian line

[Coryton]

Can anyone explain what the signal in the image below is for?

 

 

 

It's just beyond Barmouth station, facing trains heading towards the bridge. It appears to illuminate just before a train heads towards it, and stays on for a while afterwards. It doesn't seem to illuminate for trains going the other way. There is another one a little further down the line on the other side. 

 

It's not something I recognize, and it is particularly curious given that the line has generally dispensed with lineside signals (though I suppose that's not really true given the large number of locally monitored level crossings).

The only thing I can think of is that the indicators display the Welsh language equivalent of Close Doors (CD) and Right Away (RA).

According to the Rail Signs website it is informing the driver of the train that the Barriers are Up. Have a look at the bottom of the page of the attached website.

Barriers have gone back up indication to the driver, after he has passed over a locally worked level crossing with barriers. If it doesn't light up, supposed to stop and walk back to manually raise the barriers. A set can be found at the level crossing at Llandindod Wells.  Caused us problems when we worked diverted steel trains over there, as you passed the indicator before your train had cleared the crossing, so they had to station someone there to make sure the barriers did raise after the passage of the train.

Close Doors .... Cae Drws ...

Thanks to everyone for that. I knew RMweb would come to the rescue here.

 

I did have a go at Railsigns but not well enough obviously.

Presumably why there are two in Barmouth - one in the right place to stop a regular length train before it's got too far, and another further on for something on the longer side but a bit more of a walk back.
