Abstract:
An example includes an apparatus for releasing a railroad gate in at least two directions. The example includes a primary pivot member and a secondary pivot member pivotally connected to the primary pivot member, with one end of the railroad crossing connectable to the secondary pivot member. In the example the primary pivot member is rotable around a primary pivot of the apparatus, the primary pivot member rotable in a first direction against a first spring bias and in a second direction, opposite the first direction, against a second spring bias other than the first spring bias, andwherein the secondary pivot member is rotable around a secondary pivot of the apparatus, the secondary pivot member rotable in the first direction against a third spring bias other than the first spring bias and the second spring bias.
