The German railways, like German industry was not prepared for war in 1939, and incompetence and poor planning led to the crisis of early 1942. The efforts to alleviate the situation, while tackled with vigour and considerable expense would never make up the shortfalls of the early war years, ensuring the German armed forces could never be adequately supplied to fight a protracted war.
A common factor soon appeared, especially on the Western front, where German armoured columns were forced to drive to the battlefronts because the railways were no longer operational.
By war’s end the German railways were a barely functioning shambles, though some services were still operating remarkably efficiently. With the flow of spare parts, replacement troops, fuel, munitions and rations slowed to a trickle by the collapse of the railways the effectiveness of German forces decreased dramatically.
Six years earlier the German railways were hard pressed to supply Germany’s war needs and they never were able to. Without an adequate supply chain, no nation can win a war.
The American railroad system
The American railroad system was blessed with a generous loading gauge and consequently with fewer train movements could move greater tonnage. Thus America won the tonnage per mile war, which was to be a critical factor in 1944.
Another factor was the wear and tear on track and equipment. All combatants during the war experienced a decline in the efficiency of their railway systems under the increased traffic demands, America included. By the end of the war, many US railroads were in a bad way from these demands. Consequently in the immediate post war period many railroads were forced to spend heavily on track and plant repairs, replacement of locomotives and rolling stock without any assistance from the US government which was spending its tax dollars on airports and highways.
Consequently some railroads went into insolvency or were forced to amalgamate with their competitors. The replacement of worn out engines was another problem and proved to be prohibitive. Companies were faced with replacing large numbers of steam locomotives, not a cheap option by any stretch of the imagination. Diesel locomotives were a cheap option and the railroads embarked on a massive dieselization programme. Unfortunately for the railroads a lot of the first generation diesels weren’t much good and they were forced to replace them within ten years. This was an expense many companies could not afford, indirectly leading to more bankruptcies and forced amalgamation of some railroads.
In consequence the demands of America’s war effort had large scale and long terms effects on the US railroads and that was without the dropping of one bomb on the US mainland.
