Fringian Express Locomotive
|Mass||12.6 Tons + 7.5 Tons|
The Express Locomotive is a Railroad Vehicle. It requires a railroad network of the correct gauge to operate.
Description / Specifications
A sophisticated steam-powered locomotive – it operates as a locomotive-tender combination. It can tow a variety of loads.
Hull / Suspension
A generally cylindrical hull mounted on a chassis and primarily constructed from steel.
- Length: 13.3m (cabin length 2.1m), Width: 3.2m, Height: 4.0m (including smokestack).
- Overall Volume: approximately 170m³ (12.6 dTons).
- Unloaded Weight: 86,500 kg.
The overall volume measures the vehicles maximum dimensions and includes track clearance and the width of the transmission system (side-mounted external cylinders). The enclosed volume of the contoured hull is substantially lower.
The vehicle is fitted with multiple large driving wheels set onto a series of axles and connected to the boiler by rods and pistons. Unpowered wheeled trucks help support the weight of the hull and the machinery.
- The vehicle is designed to operate on rail networks. The gauge (the distance between the inner faces of the two rails) for railroad networks within the Distant Fringe is generally 1.5m and most examples of the locomotive are built to match that standard.
Power / Transmission
A very large high pressure boiler, generating steam by burning combustible fuel to heat stored water. The steam powers cylinders connected to the drive wheels. Cold-starting the locomotive can take many hours and requires hundreds of liters of water to be boiled until operating pressure is reached.
- The locomotive vents smoke, soot and steam. It is noisy and spits grease and hot water.
- Cruise Speed: 120 kph, Top Speed: 165 kph.
- Range: 900 km at Cruise Speed, 700 km at Top Speed.
The Express Locomotive typically tows a large train of wagons or over long distances. Locomotives and wagons have an automatic coupling system. The linkage also includes pressure hoses that are connected to the towed wagons and operate their brakes.
- Maximum towing weight is approximately 490,000 kg (equivalent to 10x fully loaded passenger carriages), including the loaded weight of the tender. Greater loads may be moved but this places stresses on the locomotive that may cause a catastrophic loss of control.
- Two or more locomotives may work together in order to move larger trains of wagons.
Crew / Passengers
The crew compartment consists of an enclosed rear-mounted cabin fitted with clear windows and contains two crew positions, though there is adequate room for an additional assistant or passenger. The vehicle has basic environmental protection (the hull is weatherproof but is not sealed: the cabin rear is open). The driver's position is fitted with basic mechanical controls. Gauges provide data such as internal pressure and forward velocity. The second crewmember operates a conveyor belt system which ensures that a steady supply of fuel is provided to the boiler.
The interior of the cab has many areas where small items may be stored.
- Cargo Storage: approximately 1.5m³.
- Maximum Load: restricted by available internal volume only.
Headlights and running lights, and a steam whistle. Locomotives may be fitted with animal fenders and spark arresters
A wagon that is permanently hitched to the locomotive and carries its solid fuel and a reserve of water. Floor plates bridge the gap between the locomotive and the tender.
Hull / Suspension
An open topped box-shaped hull primarily made of steel.
- Length: 8.5m, Width: 3.2m, Height: 3.7m.
- Overall Volume: approximately 101m³ (7.5 dTons).
- Unloaded Weight: 24,500 kg.
The overall volume measures the vehicles maximum dimensions and includes track clearance. The enclosed volume of the hull is rather lower.
The tender is fitted with wheels set onto axles.
- The vehicle is designed to operate on rail networks.
The tender has no internal power source.
Tenders are unpowered. They are moved by being attached to a railroad locomotive.
- The Tender has an automatic coupling system. The linkage also includes pressure hoses that connect to the locomotive and operate its brakes.
The tender carries a supply of solid fuel and a large reserve of water for the locomotive's boiler.
The cargo area of the tender is an open-fronted open-topped box. A hopper holds solid fuel and a large tank holds a reserve of water which can be transferred to the locomotive's internal tanks via pipework. A narrow walkway runs the length of the tender and gives the crew access to the towed wagons.
- Cargo Storage: 41m³ (3 dTons) fuel hopper, 35m³ (2.5 dTons) water tank.
- Maximum Load: 68,000 kg.
History / Background
A large surface transport vehicle designed for large scale logistical operations. It is designed to tow cargo wagons or passenger carriages. Locomotives of this type often bear a distinctive livery.
Although the vehicle is manufactured at a relatively low tech level and uses basic materials the design has been perfected over millennia and all of the engineering aspects are well-known and thoroughly understood. The locomotive is relatively efficient and reliable for its era.
