Have you been able to find the complete report?
Sadly no, if anybody else is able to source it I would be interested.

I have one question...wouldn't you agree that the SD70ACe made for Pilbara duty is an outlier? Locomotives designed for that work were heavier and had other modifications that made them suitable for mine haul duty that were not present in those used by the Norfolk Southern.

That I can't comment on, as I am not a US diesel expert.

Given the diversity of data on the Internet, my main requirement was to source data either from the railway company or alternatively the manufacturer for the particular type of locomotive. As you have suggested there does seem to be some diversity of specifications between different railway companies due to customizations made to their locomotives.

If you are able to provide data from a "reliable" source that better represents the NS locomotives, then I am happy to look at it.

I was actually thinking of trying to find a contact phone number for the NS in the USA and talk to someone about getting a copy of the report....I'll try, may take some time.

Gads, Peter, I'm not any kind of an expert on any of this stuff, --- at least you have considerable knowledge of physics, coding, and goodness knows what else ( web page construction for one )...meself...I'm continually ridin' the rails in the smoke and cinders behind everyone else in these here parts, playing catch-up. I'll try to find a good source. http://www.elvastower.com/forums/public/style_emoticons/default/hi.gifRegards, Gerry

That would be good, especially if they are willing to share any information.

What kind of report needed?

Witnessing the last versions of ORTS I observed the tractive force of diesels is gradually going down from notch 1 to 0 (and maybe notches higher up), this is horrible in operational terms as it takes forever to get the RPM down and so makes me wonder if this is even correct. AFAIK the generator and traction motors get disconnected when going down from some higher notch to zero. In the current way I can close the throttle and the train still accelerates for some seconds, how did this idea came about?

This may help in getting the performance for F7s: http://users.fini.ne...lais/EMD-F7.pdf

Performance is no problem here, but engine operation. Zero throttle means zero tractive force, isn´t it? Waiting for the RPM to go down (independant of RPM change speed) could be dangerous if approaching a station or red signal or even doing emergency brake.

This problem is currently present in version U2020.05.06-0551 and nearby builds.

Looks like the fix "disappeared".

Uploaded again now, so hopefully it should be available shortly.

Thanks for bringing it to my attention.

Let me explain my point of view. You said:


As we still have objections if pure motive force calculated by OR internal calculations is good then maybe it is not a good idea to test it with all resistance forces as ie. we can have underestimated resistance forces and overestimated power forces and get good result with a bad output data.

What we can do is simply compare OR motive force output values for different locomotives with different eng configurations (ie. with or without DieselEngines section) and compare it to real data (sometimes hardly available, I know, but railway fans community is big, we can search and ask for help).

Below is a real life motive force output for SD40-2 locomotive. I have the same for GP40-2. This charts can be plotted and compared to net motive force output (wheel to rail) generated by OR. Then we can tweak it to find best correlation.

traction.JPG

If we would be able compare as many locos as possible (worldwide) then we can get reasonable output data OR generates for basic eng configuration. And I am sure that one calculation will be not enough as certain types of locomotives differs significantly (DC, AC, hydraulic transmission, mechanical transmission) so we would need different formulas for each type.

After that we can start real life scenarios tests but with confirmed motive force output values we would be able to tweak resistance forces (weather, friction), adhesion and so on.

Does it make any sense?

PS

For those interested below is SD40-2 motive force output plotted from above chart. Change ',' to '.' idle and notch values to appropriate numbers from your throttle controller and it is ready to paste to your ORTSTractionCharacteristics table for SD40-2 locomotive.
