In looking at that picture, and being an engineer, I think I know the reason why.
There are four pairs of main driving wheels (or maybe more) shown. They are coupled by the tie-linkages between them. Assuming that the driving wheels are 3-4 ft. diameter then there is a length of almost 16 feet long that must remain in a straight line.
When going around a sharp curve, any flanges would have to have a lot of slop to keep the flanges from hitting real hard on the rails.
For example the loco taking a left hand curve the left hand wheels would want to drift off the left edge of the left rails and the right wheels would want to drift off the left side of the right rails.
What they did was make the driving wheels extra wide to keep them on the tracks but then use the trucks (the cluster of small wheels at the front and rear of the loco) to keep the locomotive centered over the tracks.
