My SD70 project is now coming along, after many months delay;
hope to have it ready for full release in 2~3 weeks.
The cab is nicely detailed (see attached images) &
the train is fully working with 4 units lashed up to 128 coal hoppers;
Items still lacking: misc FIRE & ICE screen functions;
misc accessories (bell/horn buttons, light switches, etc);
conductors left side of the cab; help screen.
The sounds are very pleasing to the ear, if I say so myself,
with prototype engine noise, bell, horn, & radio clips.
It feels like a 'King of The Road' on
SMIKE's BlueRidge run, or Steve Green's Desert Run.
Any willing ALFA/BETA Testers?
If so, send me an email & I'll forward the latest WIP.ZIP

After introduction in 1992, EMDs SD70 locomotives quickly became a severe duty standard;
later more powerful models (SD80, SD90 to 6000hpwr 4476kwat) have proven less practical;
the series boasts the first practical application of AC motors in heavy freight service;
as of 2006, over 3000 SD70s have been built, both AC & DC units, mostly for UPRR & BNSF.
Cabs come with either an AAR style or desk style panel, tear-drop or square windshields,
& are typically outfitted with a fly-by-wire control system that is known as FIRE & ICE,
(FunctionIntegralRailElectronics & IntegralCabElectronics), replacing traditional gauges
with multiple display screens driven by industrial-hardened PCs running a WinXP variant,
that are networked with various sub-system controls: Engine, Generator, Invertors, Slip,
Compressor, Brake, Auxliary, EndOfTrain, AutoTrainControl, DistributedPowerUnitComs.....
Primary market competition for the SD70 is the GeneralElectric ES4400 locomotive series.
This is a software simulation of EMDs SD70MAC,SD70ACE diesel electric locomotive series,
depicting control equipment typically installed on the units & common operator practice,
utilizing information from substantial research to genericly model the prototype, though
various liberties were taken with the cabs display screens & the rear panel, as required
to allow for program limitations, estimated operating characteristics, several unknowns,
authors personal preferences, or for added interest/illustration through the simulation.
