Laying panels after a derailment: Track crews are laying panels around the curve just north of Honolulu Creek after a derailment. Although pre-built track panels can save a lot of work in rebuilding, when laying them around a 10 degree curve like in this photo it can be a slow process. This is due to the fact that the inside rail gains 1" every 100' per each degree of the curve. This often necessitates cutting the low rail (note the rail saw on the yellow box) after every 3 or 4 panels to keep the rail ends of the panel fairly equal.
