There were two derailments at the interlocking plants during the year.
One occurred at Diablo and the other at the Pontoon Bridge at Paraiso.
There were also two derailments at hand throw pipe connected derails,
one at Mt. Hope passing track and one at Tower ‘‘R,’’ Gamboa.

There were 34 reported signal failures for the year from various causes -
at the interlocking plants compared to 36 last year. Of these, 24, or
about 70 per cent. occurred at the Pontoon Bridge. Considerable delays
were also reported during the month of January, 1920, in closing the
bridge on account of rail wedges not dropping into place. ‘This- was caused
by the bridge bumping the abutments when opening and closing, thereby
- throwing the apron girder about three or four inches out of alignment
at the extreme end.

Due to the increased costs of labor and material the cost of maintaiping
railway signals has increased about twenty per cent. over last year.
