The normally clear position is theone most in favor. Signals stand in the stop position with the nor-mally at danger method, until a train approaches theentrance to a block, when, if the block is clear it willautomatically change to proceed, the change taking-place in view of the engineer, with his train far enoughaway from the signal to avoid delay, then just as thelocomotive reaches the signal it automatically returns tostop, remaining in that position until that train is outof the block and another train is ready to enter it. En-gineers are expected to see to it that the proper changesdo take place, because failing so to do, it would indicatethat they were not in order, and the fact shoul
