3801 @ Thirlmere Railway Museum

Hello and welcome back to the channel! Today, we're going to be diving into the world of locomotives, specifically exploring the history and features of one of the most iconic steam engines of all time - the 3801. To truly appreciate the significance of this steam engine, we have to go back in time to the early 20th century. In 1927, the New South Wales Government Railways Commission made the decision to create a new class of express passenger locomotives, and tasked the Chief Mechanical Engineer, William Thow, to design and develop a prototype. The result was the 3801, which was completed in 1935. 3801 was an innovative marvel of its time - weighing a staggering 264 tonnes, and measuring 33.91 metres in length and 4.27 metres in height. It was a four-cylinder, simple, non-condensing steam locomotive that used triple expansion to increase the efficiency of the engine. The locomotive's valves were actuated by a rocking camshaft, which was patented by the engineer responsible for the project, Dr. Harold L. Clapp. The design stood out with its dramatic streamlined body, creating an impression of an impossibly speedy, unstoppable force. This train wasn't just a technological innovation but a powerhouse of utility and capability as well. The locomotive was designed to cover long distances at high speeds, and could reach a maximum speed of 140 km/h. It was optimized for running on steep gradients, with favorable variable cutoff and ample power output made possible due to its advanced valve gear. In its heyday, 3801 reliably served for over 30 years, transporting travelers from all over to different parts of Australia while making quite a lasting impression on all those who witnessed its operation. As the years went by, the steam engine 3801 unfortunately was phased out of service. Luckily, a group of dedicated train enthusiasts fought to preserve the legendary locomotive from dilapidation and to keep its memory alive. After surviving several failed attempts at restoration, in 2021, following another successful restoration, 3801 can now be seen making its way across the country on special trips and tours, much to the delight of enthusiasts and curious newcomers alike. And there you have it, the story of the legendary steam engine- 3801.
