As small as this locomotive is, Locobase wondered if it was intended for street railways. But the illustration shows it lettered for a mainline railroad. In any case, the riders did not ride in Spartan conditions. "The inspector's room ...is fitted with toilet-room complete, writing desk, three drawing-room car seats, one sofa, lamps, books, etc. The inside wood work is of mahogany, and the room is furnished in regular drawing-room-car style."
Yet there was a functional intent to this conveyance and Schenectady provided for that as well, installing heavy plate-glass windows in the door and to either side of the door that extended down to a foot off the floor, "...affording an unobstructed view of the track." And a large window separating the engineer from the inspectors allowed the former to see past their comfy chairs when the locomotive was running inspection-room forward.
The weights cited in the specifications are those supplied by Schenectady in their catalogue. The 1927 diagram book shows weight growth; weight on the single pair of drivers rose to 32,300 lb (14,651 kg) while engine weight climbed to 75,700 lb (34,337 kg).
Locobase 11154 shows the Transit as it was delivered by Schenectady in 1899. As might have been guessed, this little inspection engine with the single set of drivers must have faltered when challenged by any kind of grade.
So the D&H updated the design more than twenty years later with a bigger firebox that included water tubes providing 7.94 sq ft (0.74 sq m) of additional heating surface area. Its drivers also gained two inches in diameter.
After another eleven years, the Transit was scrapped in September 1899.
