Step 5: Rail-end Alignment (cont'd)
Peak (Vertical Alignment): Wood ties
. Tap in 1 wedge und.er each side of each tie plate to
either side of the gap... just enough so that each tie
plate is snug up against the rail base
. Place a welder's straight-edge across the gap
centered on the running surface. The clearance
between the end of the straight edge and the running
surface is how you measure the'peak'
. Check the peak with a Starrett taper gauge. For
wood ties it must be 3.2 mm (1/8 in)
. Taking into consideration what you saw when you
eyeballed the rail-ends... and what the straight edge
indicates... adjust the wedges until you have the
correct peak at both ends ofthe straight edge
o or... adjust the peak using a 'rail raiser', if available
. If a rail-end is too high (without wedges), lower it by
jacking up the high rail with a track jack placed 8 to
12 ties back from the rail-end
Caution!
o Do not to 'hump'the track! Slack offspikes!
o The track jacks must remain in place until the weld has
cooled down below 370"C (700'F).
o Never step on the rail during alignment.
o Don't step on the ties in the weld area until after the pour,
3.2 3.2 mm (1/8 in)
