Remedial Action 5 includes complete crossing/track rebuild, as required.
Turnout Defects
The portion of the track covered by this rehabilitation plan includes 48 turnouts. Many of these are
difficult to operate, out of adjustment, and have loose or defective parts. Remedial Action 9 (Restore
Turnouts) includes allowances for general turnout rehabilitation.
Washouts Under the Track
Heavy rain runoff occasionally washes out ballast and subgrade beneath the track in three areas along
the Main Line. Nine small washes have occurred in the last 3 years in the Main Line between Sta.
162+80 and 169+70. One small washout occurred near Sta. 253+40, and a deeper washout just past
that point. This is one area in which further study will be required to determine the most cost effective
way to either eliminate the probability of future washouts, or at least minimize possible track damage.
Remedial Action 2 includes a general plan for correcting drainage problems at these washout areas.
Skewed Ties
Some areas of the Main Line (mostly between stations 200+00 and 250+00) have skewed (crooked),
bunched, and misspaced ties. This situation is caused by the following:
1)
Low density ballast that cannot resist tie movement.
2)
Cribs (space between the ties) not fully filled with ballast, further reducing resistance to tie
movement.
