Due to numerous loose rail joints, a bolt tightening machine should tighten all track bolts. During this
operation, all defective bolts and joint bars should be replaced.
Along with bolt tightening, all high spikes should be driven down and all defective spikes replaced. This
will minimize the number of ties that drop down when the track is raised during surfacing.
However, it is not recommended to either pull any spikes driven in the slots of angle bar type joint bars, or
pull or add any spikes in ties with an incorrect spiking pattern. The combination of tie
straightening/respacing, additional ballast, and application of rail anchors included in this rehabilitation
plan should be sufficient to prevent any future tie movement due to incorrect spiking. Further, there
would be significant potential for long term tie damage due to pulling spikes (even if old holes are
plugged).
Both operations (for bolts and spikes) should be performed prior to any ballast unloading or surfacing.
