In search of the missing Labuan Railway Tunnel entrance

I guess i  have actually found it 10 years ago 

and totally forgotten about it 

until i saw a Facebook post about it. It was found after doing an image overlay of a rough map 

i got from either the Labuan or Chimney Museum on the Google Earth 

and later confirming the spot with a photo taken form a hill just opposite it 

since the location of the coal mine Railway tunnel entrance 

is now a security area of the Army.

The photo of the map i took from the museum

The image overlay on Google Earth

and the dash of the railway line and tunnel on the map matches the odd bushes
