(zoom in!)

Two double-headers on the Trans-Gooiw Railroad passing each other in the hills, dragging long freight trains behind them, during the early days of the Pan-Mellanus Oil Crisis.

More mellanoid trains: Guz's Model Garratt | Museum-piece carrying rocket parts | Advanced Steam Tank Engine | Guz's bigger model Garratt | Tram and Coal Mine loco sketches.

The diesel-hydraulic at the front of the foreground consist, already somewhat old and tired by this point, dates back to around the time period that steam engines were originally retired on Mellanus. It's not very fuel efficient as it is, and with the oil rations, diesels can not handle the trains on their own any longer.

For a few years now the railroads have been taking their steam engines out of mothballs and museums, as coal was comparatively dirt-cheap. Still though, the various maintenance and operational complexities of running steam locomotives resulted in a lot of losses for the railroads.

Pictured here behind the diesel is an early attempt at the Advanced Steam Engine concept, modifying a member of a very prolific and successful 2-8-0+0-8-2 Garratt class with a gas producer combustion system, more modern cylinders and valve gear, and entirely replacing the cab with an electronic control system (with the more diesel-like control stands moved to separate cabs on the tenders). The electronic control scheme allows for the steam engine to be connected to a diesel engine to be run as a multiple unit, cutting down operational costs. However, as a modified prototype, this locomotive lacks some of the other features which exemplified the Advanced Steam era, such as modular ashpans, computerized control, and precision engineering.

On the other track, moving the opposite direction, we see a double header of two steam locomotives, another 2-8-0+0-8-2 loaned from the Slaibsgloth Coal Mine Railroad, and a 2-10-2 'easy' type non-articulated loco leads the train. In this case, there is no electronic connection, so a crew of four mellanoid slimes is necessary to operate the train.

The eagle-eyed railway fans will notice that there are radiators for a dynamic brake on the diesel, yet the diesel is an electric. Diesel-electric dynamic brakes switch the traction motors into generators, and dump the electricity out as waste heat--but there's no traction motors on a hydraulic. So why the radiator fins? There's still a dynamic engine brake on the diesel-hydraulic, so it still needs to be able to dissipate heat, especially on the mountain routes.

Image 1: a typical modern electric slime tram, with adorable "streamlining" and an Advanced Steam commuter train.

The steam engine is an Advanced steam engine with the gas generator boiler fired automatically using microcontrollers, with compound cylinders, steam super heaters, etc. The driver controls the locomotive electronically from a cab at either end of the train. Advanced steam engines were developed due to skyrocketing oil prices which drove up the price of electricity and made diesel hydraulics much less cost effective to operate. Old style steam locomotives would not have been considered up to snuff and the maintenance facilities for them had dwindled, but Advanced Steam sought to solve the maintenance and servicing problems. Most advanced steam was utilized for very large scale applications like freight hauls and migration trains, but the concepts could also be employed on smaller scales.

Image 2: Locomotives of the Slaibgloth Coal Mine. These comprise about 30 2-8-0+0-8-2 Garrats, 5 Shays, and 5 "easy" (non-articulated) locomotives utilizing spare engine sets from the Garrats and spare boilers from the Shays.

The Garrats were built in 2346 A.D. and retired in 2379 A.D. (two years ago) for service bringing coal carriages from the coal pits up to the interchange at the Glooiw & North Eastern. It is unusual for a coal burning steam engine to remain in revenue service--the majority that remained in use after the development of Diesel-Hydraulics were decommissioned with railway electrification and the ones that remained were mostly converted to oil burning. The Slaibsgloth steam engines meanwhile persisted right up until the closure of the coal mine. Glooiw & North Eastern has acquired the 40 locomotives. Their fates are uncertain but railway preservation groups remain optimistic.
