A Scheffel bogie is a flexible, high-stability radial bogie designed to reduce lateral force vibrations and accommodate turning on narrow gauge tracks at high speed. It first went into service in a fleet of South African Railway (SAR) ore wagons in 1975. [2] [3] It is named after its inventor, Dr. Herbert Scheffel, [2] who designed the Scheffel bogie to facilitate the development of South Africa's 1,067 mm (3 ft 6 in) narrow-gauge railway system. The Scheffel bogie was used to set the world narrow gauge speed record of 245 kilometres per hour (152 mph) on Cape gauge tracks. [1]

A bogie is a chassis or framework that carries a wheelset, attached to a vehicle—a modular subassembly of wheels and axles. Bogies take various forms in various modes of transport. A bogie may remain normally attached or be quickly detachable. It may include a suspension component within it, or be solid and in turn be suspended ; it may be mounted on a swivel, as traditionally on a railway carriage or locomotive, additionally jointed and sprung, or held in place by other means.

A narrow-gauge railway is a railway with a track gauge narrower than 1,435 mmstandard gauge. Most narrow-gauge railways are between 600 mm and 1,067 mm.

<span class="mw-page-title-main">Shinkansen</span> Japanese high-speed rail system

The Shinkansen, colloquially known in English as the bullet train, is a network of high-speed railway lines in Japan. Initially, it was built to connect distant Japanese regions with Tokyo, the capital, to aid economic growth and development. Beyond long-distance travel, some sections around the largest metropolitan areas are used as a commuter rail network. It is owned by the Japan Railway Construction, Transport and Technology Agency and operated by five Japan Railways Group companies.

<span class="mw-page-title-main">Tilting train</span> Type of train that can tilt in curves

A tilting train is a train that has a mechanism enabling increased speed on regular rail tracks. As a train rounds a curve at speed, objects inside the train experience centrifugal force. This can cause packages to slide about or seated passengers to feel squashed by the outboard armrest, and standing passengers to lose their balance, or in such excessive speeds, could even cause the train to derail. Tilting trains are designed to counteract this by tilting the carriages towards the inside of the curve, thus compensating for the g-force. The train may be constructed such that inertial forces cause the tilting, or it may have a computer-controlled powered mechanism.

<span class="mw-page-title-main">Track gauge</span> Spacing of the rails on a railway track

In rail transport, track gauge is the distance between the two rails of a railway track. All vehicles on a rail network must have wheelsets that are compatible with the track gauge. Since many different track gauges exist worldwide, gauge differences often present a barrier to wider operation on railway networks.

<span class="mw-page-title-main">Transporter wagon</span>

A transporter wagon, in railway terminology, is a wagon (UIC) or railroad car (US) designed to carry other railway equipment. Normally, it is used to transport equipment of a different rail gauge. In most cases, a transporter wagon is a narrower gauge wagon for transporting a wider gauge equipment, allowing freight in a wider gauge wagons to reach destinations on the narrower gauge network without the expense and time of transshipment into a narrower gauge wagons.

<span class="mw-page-title-main">Break of gauge</span> Meeting place of different width rail lines

With railways, a break of gauge occurs where a line of one track gauge meets a line of a different gauge. Trains and rolling stock generally cannot run through without some form of conversion between gauges, leading to passengers having to change trains and freight requiring transloading or transshipping; this can add delays, costs, and inconvenience to travel on such a route.

The Hokkaido Shinkansen is a Japanese high-speed Shinkansen rail line that links up with the Tōhoku Shinkansen in northern Aomori Prefecture in Honshu and continues on into the interior of Hokkaido through the undersea Seikan Tunnel. Construction started in May 2005; the initial Shin-Aomori to Shin-Hakodate-Hokuto section opened on 26 March 2016. The section of the line to Sapporo is scheduled to open by fiscal year 2030. The line is operated by the Hokkaido Railway Company.

Co-Co is the wheel arrangement for diesel and electric locomotives with two six-wheeled bogies with all axles powered, with a separate traction motor per axle. The equivalent UIC classification (Europe) for this arrangement is Co′Co′, or C-C for AAR.

<span class="mw-page-title-main">Variable gauge</span>

A variable gauge system allows railway vehicles in a train to travel across a break of gauge between two railway networks with different track gauges. For through operation, a train must be equipped with special bogies holding variable gauge wheelsets which contain a variable gauge axle (VGA).

<span class="mw-page-title-main">Rollbock</span> Railway trucks that can carry a standard gauge wagon on a narrow-gauge line

Rollbocks, sometimes called transporter trailers, are narrow gauge railway trucks or bogies that allow a standard gauge wagon to 'piggyback' on a narrow-gauge line. The Vevey system enables a coupled train of standard gauge wagons to be automatically loaded or rolled onto Rollbocks, so that the train can then continue through a change of gauge.

<span class="mw-page-title-main">Bogie exchange</span> System for operating railway wagons on two or more gauges

Bogie exchange is a system for operating railway wagons on two or more gauges to overcome difference in the track gauge. To perform a bogie exchange, a car is converted from one gauge to another by removing the bogies or trucks, and installing a new bogie with differently spaced wheels. It is generally limited to wagons and carriages, though the bogies on diesel locomotives can be exchanged if enough time is available.

<span class="mw-page-title-main">Track gauge conversion</span> Change of rail tracks or rail vehicles to a different gauge

Gauge conversion is the changing of one railway track gauge to another.

The Gauge Change Train(GCT) or Free Gauge Train (フリーゲージトレイン, "FGT") is the name given to a Japanese project started in 1994 to develop a high-speed train with variable gauge axles to allow inter-running between the 1,435 mm (4 ft 8+12 in) standard gauge Shinkansen network, and the 1,067 mm (3 ft 6 in) narrow gauge regional rail network.
