Where the caution indicator placed in BG if the engineering work is more than one days and train not to be require to stop at site? A. 1200 Meter B. 1000 Meter C. 800 Meter D. 500 Meter

The correct answer is: A. 1200 Meter.

A caution indicator is placed 1200 meters before the site of engineering work that is expected to take more than one day. This is to allow trains to slow down and prepare to stop at the site. The caution indicator is a yellow sign with a black border and a black diagonal line. It is placed on the right side of the track, facing oncoming trains.

The other options are incorrect because they are not the correct distance at which a caution indicator is placed before the site of engineering work that is expected to take more than one day.
