TIES ON BRIDGE - They will "float" in position so they can be adjusted with
shims. They were adjusted as well as possible to matching heights at the center.
THE GAP - It's only 3 feet away, but the transition from regular track to the
bridge is important.  It's a weak spot where the track has to be kept level at all
times.
RADIUS ROD - The curve for the approach track will be at a 30 foot
radius.  A nylon string (from haybales) is used to measure from the pivot to a
knot.
TRANSITION FRAMING - A pair of 3-foot 4x4's is bolted to the last tie on
the bridge with lag bolts.  Thinner-than-normal ties will sit on top of the 4x4's.
TRANSITION COMPLETE - The approach track is supported with extra
ballast, the transition piece os levelled out, and rail has been bolted together.
TIE SPACER - A 5/4 x 2 inch piece of deck lumber is notched 1.5 inches
wide every 4 inches.  We will use six 4-foot pieces to space out all the bridge
ties.
SPACER IN PLACE - As you can see, the ends of the ties are very even, and
it is easy to pull out of the way if a tie needs to been shimmed to be even with
the others.
INAUGURAL RUN - Candy leads the way as her daddy rides the first train to
use the new bridge.
POSING ON THE BRIDGE - It has no trouble holding the weight of the
engine, riding car, and large engineer!
THIRTY SIX TIES - Cut to 38 3/4 inches and notched at the ends - were
prepared and loaded onto the golf cart.
