Sonic Robo Blast 2 (often abbreviated SRB2) is a platform game made within id Software's Doom engine. It is a free Sonic the Hedgehog fan game inspired by the original Sega Genesis games that "attempts to recreate their design in 3D", [ 5 ] and was the first fan-made 3D Sonic game created. [ 6 ]
Proton is developed by Valve in cooperation with developers from CodeWeavers. [2] It is a collection of software and libraries combined with a patched version of Wine to improve performance and compatibility with Windows games. Proton is designed for integration into the Steam client as "Steam Play". [3]
The Mikado type was, in turn, ousted from the top-flight trains by larger freight locomotive wheel arrangements such as the 2-8-4, 2-10-2, 2-10-4 and articulated locomotives, but no successor type became ubiquitous and the Mike remained the most common road freight locomotive with most railroads until the end of steam. More than 14,000 were ...
The 2-8-8-2 was a design largely limited to American locomotive builders. The last 2-8-8-2 was retired in 1962 from the N&W's roster, two years past the ending of steam though steam was still used on steel mill lines and other railroads until 1983. Other equivalent classifications are: UIC classification: (1′D)D1′ French classification: 140+041
On a steam locomotive, the cutoff is controlled by the reversing gear. The point at which the inlet valve closes and stops the entry of steam into the cylinder from the boiler plays a crucial role in the control of a steam engine. Once the valve has closed, steam trapped in the cylinder expands adiabatically. The steam pressure drops as it expands.
An oscillating cylinder engine cannot be reversed by means of the valve linkage (as in a normal fixed cylinder) because there is none. Reversing of the engine can be achieved by reversing the steam connections between inlet and exhaust or, in the case of small engines, by shifting the trunnion pivot point so that the port in the cylinder lines up with a different pair of ports in the port face.
He also borrowed a 'single-wheeler' from the Great Eastern Railway and, in 1868, designed two versions of a 2-2-2 arrangement with 7 ft 1 in (2.159 m) driving wheels. [3] The outcome in 1870 was a locomotive with 8 ft 1 in (2,460 mm) driving wheels, designed specifically for high-speed expresses between York and London. The British norm at the ...
In a steam engine, the firebox is the area where the fuel is burned, producing heat to boil the water in the boiler. Most are somewhat box-shaped, hence the name. The hot gases generated in the firebox are pulled through a rack of tubes running through the boiler. [1] [2]
