Peter, I will get back to you on the HEP generator information. I've got to look through my documents and gather up the info.

HEP Head End Power is of a couple different setups, In the early years this would have been oversized steam driven turbo generators equipped to steam locomotives in commuter service. Ex, CNW pacifics used on the Chicago area commuter lines. The DC Voltage was used for the car lighting systems since the cars sat still for 20 out of every 24 hours. Also the frequent stops did not allow for adquate battery charging. When diesels came along the DC came from the main generator or from a smaller auxilliary generator.

The modern HEP setup is 3 phase AC either generated from the main diesel engine that also turns the traction generator or from a seperate HEP package installed in the locomotive or in a converted passenger or freight car.

The first pioneer in HEP AC generated from the main engine was the Erie Lackawanna ordered GE U34CH. Amtrak ordered it's F40PH after seeing the success of the U34CH which was used in New Jersey commuter service.

On the U34CH this setup needed the main engine to turn at 960RPM to maintain the 60 Hertz AC frequency for the 3Phase AC power. The engine was fed fuel and the main traction alternator would be excited to the nessecary degree but the engine RPM would stay constant. My link

The EMD F40PH worked on a similar bases. These setups worked well but are very hard on the main diesel engine.

Nowadays most locomotives either have a seperate HEP unit or a inverter setup so the main engine can run in a normal fashion and not wide open to maintain line frequency.

Hello,
Could anyone advise me to show me what the whole write for the wag file should look like?

Or attach a sample wag? Thank you

CNR used steam generator units for their early diesel passenger trains with the F series engines . I think they also made some for MOW gangs that had a diesel fuel fired boiler for the steam for heat and an auxiliary generator run by a smaller size diesel for electricity . Sort of like a dual duty detachable Hep . I believe I got the model from the TS library and gave it some exhaust and sounds for the auxiliary diesel .
It's been around for many years .

Gaetan ( BLW ) has 2 CNR Steam Generator cars, 1 in green & gold and 1 in wet noodle ( black & white ).

This is a nice documentary of the U34CH and gives a good information on the operations of the U34CH in both passenger and freight modes. There is also a discussion on early HEP on steam and diesel.

Each segment is only 15 minutes or so and thus the 8 links. The program is actually only an 1 and a few minutes long.

U34CH Pt2 Part 2

U34CH Pt3 Part 3

U34CH Pt4 Part 4

U34CH Pt5 Part 5

U34CH Pt6 Part 6

U34CH Pt7 Part 7

U34CH Pt8 Part 8


PS, I started on a set of U34CH units for MSTS but have not finished them yet. If anyone can help with the Disco stripes I would then be able to release the U34CH units.

Hi Robert,

Thanks for all the information.

I will need some time to digest it all.

In a sense, you have always been able to add another exhaust in the steam generator area; it just uses the same parameters as all other exhaust(s).

What does the GeneratorFX code do different to the normal exhaust1 code ?

Is it possible to use the HeatingHoseFX to simulate a steam vent in the steam genny area; or can it only be used in a wag file ?

Sorry to bump this thread but here's another effect worth simulating that's along the lines of this topic: Smoke from a caboose or brake van.

Virtually all cabooses (brake vans in the UK) had wood or coal-fired stoves to keep the conductor/guard warm on a cold winter night. Adding the functionality of a stove-smoke emitter for rolling stock allows the effect to be added without making the caboose an "engine." Similarly, 19th-century passenger cars made before steam heat was introduced could also have the stove emitter function.
