The locomotive had two cut-outs on the roofline on the roof access ladder side, but an unbroken roofline on the opposite side.
The Series 3, 4 and 5 locomotives could be visually distinguished from earlier series by their three small square access panels on the lower sides above the battery box instead of the two larger rectangular access panels on the Series 1 and 2 locomotives.
Like the Series 2, the Series 3 also had an additional rectangular access panel on the lower sides above the second axle from the left.
