A railway indicator device is provided for indicating a condition associated with a particular section of track of a railway. The device includes a post supported in the ground adjacent the railway track which pivotally supports a swing arm thereon for movement between a raised position extending vertically abov e the post and a lowered position extending horizontally across the railway track spaced above the ground. An indicator panel, for example a blue flag indicator is supported on the free end of the swing arm for pivotal movement therewith relative to the post. The pivoting swing arm permits the indicator panel to be readily retracted or deployed by a single operator while minimizing opportunity for the indicator panel to be lost or damaged as commonly occurs with conventional designs of indicator s used on railways. |
