Class D (I) (Locobase 4016)

Data from William Bay, Danmarks Damplokomotiver (1977). Class information from []

The Swedish modelling website [] (3 July 2003) has supplied information about the four D classes of Moguls.

This first batch were produced by both German and Swedish builders -- Hartmann and Henschel & Sohn from Germany and Nydquist & Holm in Sweden -- over a period of 6 years as follows:

Year Builder Road Numbers

1902 Henschel 5981-5985

1903 Hartmann 2800-2804

1905 Henschel 6964-6968

1905 Hartmann 2935-2946

1906 Hartmann 3046-3051

1908 Nydqvist 864-871

In the 20s, a substantial conversion and enlargement of surviving D1s and DIIs produced the DIV, which see at Locobase 4020.

Class D (II) (Locobase 4017)

Data from WilliamBay, Danmarks Damplokomotiver (1977) and from Albert H Bone, "Some Recent Designs of Locomotives for Service on Continental Railways", Cassier's Magazine, 1910, pp. 561-609.

The Swedish modelling website [] (3 July 2003) says these were similar to the DIs produced a few years earlier, but they were superheated from the start. An impressive array of builders supplied engines over a thirteen-year period: Belgium's Tubize, Denmark's Frichs, Germany's Schwartzkopff, and the USA's Baldwin Locomotive Company. Popular in service, the class was affectionately dubbed the "Dagmars".

Works numbers were

Year Builder Road numbers Works #

1909 Schwarzkopff 842-851 4187-4796

1912 Tubize 865-869 1739-1743

1919-1920 Baldwin 870-885 See Locobase 14722

1920 Schwarzkopff 886-895 7261-7270

1922 Frichs 896-900 37-41

Bay's data clearly shows a Smith-type compound cylinder layout (1 HP exhausting into two LP cylinders), but the Cassier's article equally clearly shows a two-cylinder simple layout.

In the 20s, a substantial conversion and enlargement of surviving D1s and DIIs produced the DIV, which see at Locobase 4020.

Class D (II) - BLW (Locobase 14721)

Data from DeGolyer, Vol 62, pp. 1. See also Locobase 4017 for the rest of the class as built in Europe. Works numbers were 52404 in September 1919; 52434 in October; 52455, 52470-52475, 52541-52542, 52568-52572 in November.

Although the first members of this class of Moguls had been produced by Schwarzkopff in 1909, Baldwin's contribution was made after the end of World War One. According to Wikipedia, the money for the sixteen engines came from some of the cash paid by the US to Denmark for the Virgin Islands in 1917.

The specifications differ slightly, but were expressed in metric measure as well. Indeed, the specification stated "The contractor must agree to execute all the works by the building of these locomotives according to the metrical system and the detail drawings."

In the 20s, a substantial conversion and enlargement of surviving D1s and DIIs produced the DIV, which see at Locobase 4020.

Class D (III) (Locobase 4018)

Data from William Bay, Danmarks Damplokomotiver (1977). Class information from []. Works numbers were were 4369-4381 in 1910.

The Swedish modelling website [] (3 July 2003) says these were identical to the DIIs supplied beginning in the same year, but were not superheated. Actually, though, the simple-expansion layout matches that of the earlier DI design but has a larger boiler. The grate is bigger than that of the DIIs.

The class was superheated within 5-10 years of delivery; see Locobase 4019.

Class D (III) - superheated (Locobase 4019)

Data from William Bay, Danmarks Damplokomotiver (1977). []

---

Class D (IV) (Locobase 4020)

Data from WilliamBay, Danmarks Damplokomotiver (1977). The Swedish modelling website [] (3 July 2003) describes this class as a result of the rebuilding of all the DIs and some of the DIIs. The site says the boiler was enlarged, but the data doesn't support that contention.

What is true is that the grate got bigger as did the cylinder diameter.
