JR engine specs

Hi JR,
Just downloaded latest "JR engine specs" updates. I have noticed a difference for the better it seems, jr locomotives using the latest "JR engine specs" updates seem to be performing more realistically can anyone confirm this.

except for these three below:
TANE Obsolete


<kuid2:45324:100:2> dummy engine
<kuid2:45324:4381:4> GP38-2 engine no dynamic brake - (<kuid2:45324:4381:5> v5 on the DSL does not contain updated throttle figures)
<kuid2:45324:1151:1> MiJack 1200R engine


TRS19 Obsolete
<kuid2:45324:1151:1> MiJack 1200R engine
<kuid2:45324:4381:4> GP38-2 engine no dynamic brake+ - (<kuid2:45324:4381:5> (v5 on the DSL does not contain updated throttle figures)
<kuid2:45324:100:2> dummy engine


TRS19 buil-in
<kuid2:45324:6307:7> C30-7 engine -( v5 on the DSL does not contain updated throttle figures)

You can expect the very latest specs to be added to the DLS very soon (before the close of the year), I am currently finishing them up.

There are no updates to the MiJack as I am confident it does 4 mph very effectively and I cant even remember what the dummy is for but it is likely, as it's name suggests, nothing to worry about. All of the others will see an update.

Hi Justin,
Im aware of <kuid2:45324:1151:1> MiJack 1200R engine & <kuid2:45324:100:2> dummy engine these dont need the latest update of (throttle figures).


Are u able update these ones re: maxvoltage figures these are at 1700 - <kuid2:45324:6704:4> SD70M engine, <kuid2:45324:6903:4> SD90MAC engine, <kuid2:45324:6703:6> SD70MAC engine & <kuid2:45324:6803:6> SD80MAC engineim getting constant overheating
warnings (overlays in driver) on level grades, example: 2 x sd70macs 30 x 100 ton open hoppers loaded with coal at 100 ton each, not evan at full throttle.

I started a post on this myself, and JR posted some of the engine specs and I tried one and yes it did help, but not sure there still correct. The one engine I tested went from 37 MPH and picking up speed in notch 1 to 21 MPH. I tried to look on the net to see what the notch speeds should be, but couldn't find any. I still thank 21MPH mite still be a little fast in notch one on flat terrain with no cars, and know one ever returned a post to answer me.

We are talking about kn at a certain speed not speed at a certain throttle setting. You just have to do the math to find the answer.

According to my data the ES44 (from the other topic) should be putting down about 2klb force at about 21mph in power N1. If you look in the engine spec you see that notch 1 runs out at 19.3mph (8.64 m/s) with a figure of 2169.4 lb (9.65 kn) so I have followed what real world data I have as close as I can for the time being. There will always be slight variations of course taking into account sand and fuel weight at the beginning of your trial.

Let's make it simple, locomotives are diesel electric which means the engine is turning a generator or alternator, nothing like a car when first gear limits you to like 5 km/h at idle, voltage = speed and amps = torque.

Now lets say we generate 250 volts and 400 amps at notch 1 how fast will the locomotive go? well this depends on how the motors are setup, lets say we have a 6 axle locomotive in full series, this means that 250 volt output is only going to be 41.6 volts per motor and 66.6 amps per motor and lets say the locomotive only runs to a speed of about 20 km/h, lets say the locomotive is in full parallel in this case it's 250 volts per motor and 400 amps per motor, I reckon notch 1 will get it to about 40 km/h.

Cheers.

Locomotives in trainz aren't diesel electric. They are powered by code.

I couldn't imagine trying to make it all display with some degree of realism on the cab displays.

Thanks NS37 you answered my question, and I'm good with that.
