Although there is a major difference between the two batches—the first 12 engines are type 1′F2′ h2Gt — tank-engine for freight service, two-cylinder system with simple steam expansion (Zwilling) with superheating, while the remaining 8 are 1′F2′ h3Gt — 3-cylinder (Drilling)—all were put into the same class 46 and numbered 46.01 ...
A Finnish Steam Locomotive Class F1 rear tank locomotive. In this design, the tank is placed behind the cab, usually over a supporting bogie. [14] This removes the weight of the water from the driving wheels, giving the locomotive a constant tractive weight. The disadvantage is a reduction in water carrying capacity.
They were superheated and had Walschaerts valve gear. The locomotives were built by NBL and erected in the Salvokop shops in Pretoria. At the time of their introduction, the Class MH was the largest and most powerful locomotive in the world on Cape gauge, with a full working order weight of 179.6 long tons (182.5 tonnes; 201.2 short tons).
From 1936, the German railways built 28 three-cylinder 2-10-2 tender freight locomotives of class BR45, which were the most powerful steam locomotives on the system. [ 8 ] Further examples, still in regular service, are the metre-gauge DR Class 99.23-24 on the Harz Narrow Gauge Railways and the 750 mm-gauge DR Class 99.77-79 on the Rügen ...
Using the minimum amount of raw materials, and with all superfluous features stripped away, he produced in 1942 the most powerful 0-6-0 steam locomotive ever to run on Britain's railways. [10] The first twenty locomotives were constructed at Brighton railway works and the remaining twenty at Ashford railway works. Powerful and light, the Q1s ...
The LMS Stanier Class 4P 3-Cylinder 2-6-4T is a class of steam locomotives designed for work over the London, Tilbury and Southend Railway route. All 37 were built in 1934 at Derby Works and were numbered 2500–2536. The third cylinder was provided to allow increased acceleration between the many stops on the L.T.&S.R. line.
PKP Class Pt47 is a Polish steam locomotive.An improvement of the successful pre-war PKP class Pt31 class, the main difference is the addition of circular tubes in the fire chamber, thereby significantly increased boiler performance.
