Abstract
An acceleration indicator including an anti-tampering arrangement adapted to be secured to a railway freight car for detecting pre-selected destructive impacts on the the car. The indicator includes a generally hat-shaped casing having a normally obscured movable plate or flag carried therewithin by a spring biased pendulum supported on a vertical plate secured within the casing. The vertical plate also supports the anti-tampering arrangement such that when the indicator is subjected to a preselected impact, the pendulum swings clear of the flag and drops by gravity into a position where it can be observed whereat it is entrapped by the anti-tampering arrangement.
