The modifications for the A4 class
consisted of:
(1)
Replacing the original spoked wheels with disc wheels.
(2)
Increasing the width between the side sheets at the front end. This
necessitated moving the front handrails towards the rear. At the same
time, on the tenders behind 4488 to 4490, these handrails were increased
in length by 3" to 4' 6". |
(3)
Raising the height of the front and division plates to cab height and
providing a fairing.
(4)
Removing the second lamp bracket on the left side of the back.
