Tyas remarked that this design was "very like some of the French locomotives, with the exception of chimney, dome and safety valves, which were of the Prussian State Railway pattern." They "somewhat" resembled the De Glehn type of compounds.

An unusual feature was the internal dry pipe leading forward from the dome to a junction with the two outside steam pipes that dropped straight down to the valve chests. Allan valve gear operated on these chests outside of the frames.

Tube diameter is the interior measurement. External tube diameter was 46 mm (1.81").

Tyas wrote that these De Glehn cross-compounds "worked the fastest and heaviest trains for some considerable time."

Tube diameter is the interior measurement. External tube diameter was 46 mm (1.81"); the resulting "water side" area was 1,335 sq ft (124.03 sq m) and with firebox heating surface area, 1,428 sq ft (132.67 sq m).
