Title: Pre-plating of wooden railroad ties

Abstract: Methods are disclosed by which wooden railroad ties are pre-plated prior to use in constructing and/or repairing railroad lines. Methodology disclosed comprises placing two plates on top of each of a succession of wooden ties, temporarily positioning disclosed one of the two plates on each tie with a distance or spacer template temporarily clamping the two plates accurately to the tie using a jig, starting a field spike and a gauge spike (usually with one or more sledge hammers) into each wooden tie through the selected apertures in each plate, and further driving the started spikes into the associated tie (usually using a jackhammer). Typically, the field spike is located outside the field flange of the plate and is driven until the head of the spike is contiguous with the plate. Typically, the gauge spike is displaced through an aperture in the gauge flange of the plate until the head is about 11/2 inches above the plate.
