Standard Eastern Rail
Sometimes referred to as Eastern Standards, the Standard Eastern Rail is a term used to describe a series of standardized train types with preset characteristics by Class, which include gauge, voltage, and characteristics as specific as the distance between doors or the total amount of carriages per train.
The SER was created in 1955 as part of an innitiative lead by the Riamese Government, which aimed to create a set of standardized train characteristics throughout Riamo, hoping it would reduce development, planning, and construction costs for future updates to the different rail-based transportation systems.
As of 2021, the national railway networks of Riamo, Hoterallia, and Gran Rugido have been standardized following the SER standards, with many rail-based transport around the world also having been built to SER standards.
Classes
While the list of standard train classes has been reviewed in multiple occasions, its fundamentals have not changed since 1955. The following list represents the original 17 classes envisioned by the SER creation documents. As per convention, all classes feature 1500mm standard gauge unless otherwise specified.
Notes:
- "Catenary" refers to overhead non-rigid wires
- "K" is often used to refer to DC currents
- R is used to mark the classes not banned or advised against in Riamo, as current legislation in the country prohibits the use of some classes for further simplification efforts
- A - High Speed Rail
- AS R - Shinkansen-Type High Speed - 3kV Catenary, 250-400m long trains (up to 350 km/h)
- A1 - Standard High Speed, long - 3kV Catenary, 200-260m long trains (up to 320 km/h)
- A2 - Standard High Speed, short - 3kV Catenary, 130m long trains (up to 320 km/h)
- B - Heavy Rail
- B1 R - 3kV Catenary, 5 carriage variation
- B2 - 3kV Catenary, 8 carriage variation
- B3 - 3kV Catenary, 10 carriage variation
- BT - 3kV Catenary, third rail (exclusive for mountain trains or mining operations)
- C - Commuting/Short Distance Rail & Trenchways
- C0 - non-electrified, 40-80m long (in desuse)
- C1 - 3kV Catenary, 40m long
- C2 - 3kV Catenary, 80m long
- C3 - 3kV Catenary, 120m long
- C4 - 3kV Catenary, 160m long
- M - Metros & Subways
- M1 - 1500V DC, 102m long, 6 carriage subway trains (extremely common)
- M2 - 1500V DC, 130m long, 8 carriage subway trains
- M1K - 20kV AC, 102m long, 6 carriage subway trains (in desuse)
- M2K - 20kV AC, 130m long, 8 carriage subway trains (in desuse)
- MM - Monorail, 20kV AC, 102m long, 6 carriage trains
- T - Surface Trams
- T3 R - 3 cars, 600V DC Catenary
- T5 R - 5 cars, 600V DC Catenary
Benefits
While the SER stabdards have become synonymous with rail transportation in nations like Riamo, some countries remain skeptical about the idea, with many considering it as a matter of national security to keep different rail characteristic across international borders.
However, it is to be mentioned that those countries which have implemented the SER standards across their systems have experienced a steep decline on research, development and construction times and costs theoughout their systems[4] [5], mostly due to the lack of a preparation and study phase to determine the type of transport to be used[6].
The reduction in costs has also had an impact on air travel, with the battle between air and rail not being such a reocurrent theme in the east as it was been in the west [7] [8].
