Overview who/what was it
The South African Railways & Harbours (SAR&H / S.A.S. en H. / S.A.R. & H.) provided an organised military contribution within the Union Defence Force structure during WWII, formed to protect and operate vital transport (rail and harbour) services and to provide manpower and specialised units for the war effort.
________________________________________
Purpose & strategic importance 🛤
SAR&H was critical to the Unions war logistics: moving troops, supplies and equipment across South Africa, maintaining port operations, and protecting transport lines from sabotage. Control of rail and harbour infrastructure was strategically essential for Allied shipping and internal mobilisation.

Organisation (WSU / KDB) 📋
Names / Abbreviations: The service is referenced in period material by English and Afrikaans names War Services Union (WSU) and Krygsdiensbond (KDB) often shown together on emblems (W.S.U. / K.D.B.).
Re-establishment / wartime formation: A formalized SAR&H military brigade/unit structure was (re)established early in the war period sources note re-establishment on 1 April 1940 with HQ at Johannesburg. It was organised to include infantry battalions and armoured-train elements.
Subunits: wartime organisation included infantry battalions, armoured trains and other railway protection detachments structured to both operate and defend rail lines and ports.

Roles, duties & typical activities 🔧🚆
Railway protection & security: guards and patrols of lines, bridges and junctions, anti-sabotage work.
Armoured trains: mobile, armoured railborne formations used for patrol, escort, and local defence on threatened sections of track. Sources reference multiple armoured trains as part of the brigade organisation.
Logistics & movement: SAR&H personnel and resources were critical to moving South African troops and matériel to ports and staging areas for overseas deployment.

Insignia & badge details 🦌🎖
A distinctive badge is recorded in archival descriptions: on a navy-blue background a green oval scroll (gold outline) bears a wheel with wings surmounted by a Springbok head; the gold letters W.S.U. appear to the left of the Springbok and K.D.B. to the right; on lower sides are the abbreviations S.A.S. en H. and S.A.R. & H. respectively. This emblem ties the railway/harbour service identity with the War Services Union / Krygsdiensbond markings.

Where & when they served (high level) 🌍
The SAR&H war service was primarily domestic protecting and operating internal and coastal transport nodes essential to the UDF and Allied shipping. Elements (personnel, equipment and organisational expertise) fed into wider UDF mobilisations and overseas convoy/port support as needed. The brigade organisation (including armoured trains and infantry battalions) was active during the key earlymid war years after 1939/1940.

Notable characteristics & significance
Dual civilmilitary role: SAR&H units combined professional railway/harbour expertise with military organisation making them uniquely suited to logistical and defensive tasks that conventional infantry could not perform as effectively.
Flexible mobile defence: armoured trains gave a rapid-response, mobile platform on the rail network for patrol and local defence a pragmatic adaptation to the geography and infrastructure of South Africa.

Post-war / legacy 🕰
After WWII, the SAR&H continued as the national transport authority and many wartime wartime structures were demobilised or reabsorbed into civil organisation. SAR&H later evolved through reorganisations (became South African Transport Services in 1981; later Transnet). The wartime contributions of railway & harbour units remain a specialised chapter of South African military logistics history.
