Upside down triangles?

[Tintinfan]

Greetings,

 

I have been trying to find out more about the signs, lamps and signals of Onuma station for my layout. One of the things (of a few) that I can't seem to find any information on is an upside-down yellow triangle sign. At best guess, I think it could be a stop indication sign for signals placed in odd locations. I have been able to find it at a few other stations on the Hakodate Mainline and other lines in Hokkaido, but have found no name or information on these. It looks like this;

 

 

You can find images of the real ones on the first few images here for example - and at quite a few stations along the line if you take a ride on the Hakodate Mainline for example.

 

Any help would be much appricated!

I cannot find it in any of the links you gave. Edit- found them.

 

I assume though that it is a beacon. Which is used a lot these days on simple bi-derictional signaled track like most of Hookaido. Especially when they are 2 aspect red and green. The beacon acts as a yellow caution so the driver treats the next signal as red until viewed.

 

Or I could be completely incorrect.

 

Edit/ Could also be the magent/transponder location in front of a signal. Due to heavy snow, these get hidden and may need to be located visually by the driver.

 

Still a guess.

Thank you very much for your suggestions! It seems this guess of yours is correct, I have found an article with an image of my yellow and black upside down triangle explaining how the sign is for the ATS beacon before a home signal. With this I am sure I can get all the information I need now. Thanks again!

Could also be the markers for the beginning and the end of ATS-fitted sections

Left could be "ATS in" and right "ATS out"
