South West African Class Ha

The South West African Class Ha 0-6-2T was a group of small steam locomotives built in Germany in the early 1900s for use in German South West Africa (now Namibia). Ten narrow-gauge 0-6-2T engines were constructed by Henschel and Son in 1903 and delivered in 1904. They were leased to the Otavi Mining and Railway Company, which operated a 600 mm gauge railway across the Namib Desert from Swakopmund to Tsumeb.

Numbers and service
- Builder numbers were originally 11–20, but the locomotives were renumbered by the Otavi Railway to 21–30 on their cab sides.
- The class served the Otavi Railway line and were used as part of the railway system serving the Otavi mining area.
- After World War I, the German colonial railways in GSWA came under South African administration, and by 1 August 1915 control of railway operations moved first to a Windhoek directorate and later, on 1 April 1922, to the South African Railways (SAR). Of the Class Ha locomotives, only no. 22 survived the war into SAR service, retaining the Ha class designation.

Manufacturer and design
- Ten 0-6-2T steam locomotives were built for GSWA by Henschel in Germany, delivered in 1904 as Class Ha.
- They were similar in size to the earlier Jung locomotives but had larger boilers and used Allan valve gear.
- The Ha class was the first GSWA locomotive class built by Henschel.

Notable details
- One locomotive, No. 27, was rebuilt at the Usakos workshop for Otavi Railway’s fast passenger service by removing the side-tanks and coal bunker and attaching a tender. Two Jung locomotives were rebuilt in a similar way.
- The Ha locomotives operated on the Namib Desert route that linked Swakopmund and Tsumeb.

Other Otavi Railway types
- Besides the Class Ha, other locomotive types reportedly served on the Otavi Railway, including a small side-tank engine with a tender and two Patentee-type shunting engines (Nos. 28 and 29). Some sources on these locomotives are unclear, but they are thought to have been built around the same era, possibly for construction or shunting duties.

Summary
The South West African Class Ha represented an early group of German-built steam locomotives used on the 600 mm gauge Otavi Railway in what was then German South West Africa. Built by Henschel in 1903–1904, these 0-6-2T engines were important for the region’s mining and transport needs and partly survived into the SAR era, with No. 22 continuing in SAR service after the war.
