Driver mode slower?

[gordonfan248]

Hello, I've been playing primarily in DCC mode since TRS2004 was out. I would like to get into more in depth driving using Cab mode, I am looking at buying the RailDriver control console (any one have this?? any reviews?) I was playing around with the cab controls to see if I can understand what I'm to do, and with the same consist, in DCC mode, I can get the train to 143kph, but in cab mode, I (think) I have all the different brakes (sorry, kinda new to the terminology) released, but I cannot get it over 109kph. Am I missing something??

Any input is greatly appreciated.

Thanks!

I have the RailDriver, and it's great. I never used the cab mode without it, and haven't noticed the difference you've pointed out. Interesting observation.

I'm almost sure it's something I'm doing, since I'm so new to the Cab mode, I've made sure the trainbrake, independant brake is released, and the dynamic brake has to be released in order for me to move at all. Is there something else I need to do?

It also takes about 3 times as long to get up to the (slower) speed, when compared to the DCC Mode.

I run 2004 too and I have noticed the same thing in cab mode.
I ran a 4000 ton coal load on the Clovis route starting at the eastern end, with a slight up gradient.
With DCC it was no trouble to get rolling and got up to the 70 MPH speed limit no probs.
When I went into Cab Mode it was really working to get it moving and could do no better than 35 MPH on the grade.
I have always thought DCC was a bit unrealistic in the loads you can pull and the speeds you get.
The Cab Mode seems to be a lot more near the mark.
Just IMHO,
Cheers,

Yeah, I think the cab mode is designed to give you a more realistic ride, DCC just moves 'em like your model train sets.

DCC mode uses the Motor container parameters in the enginespec kuid for the loco. Specifically, it uses maxspeed, max-accel and max-decel as limiting values. Cab mode uses the throttle-power or steam containers to determine accel and speeds. Cab mode is supposed to replicate real physics of the train while DCC mode gives the user simpler, easier control.

I have Raildriver and love it. I have noticed the differences that you mention and think that Cab mode is much more realistic. It'll take a little practice to get used to Cab mode, but it's much more enjoyable for me and the Raildriver just adds to the experience IMHO.

I don't have a raildriver, but I love driving the locos in cab-mode in 2006. The biggest drawbacks are imbalances between pulling power in DCC vs CAB, and the fact that sometimes, content creators attach a diesel enginespec to a steam loco, making for all kinds of operational anomalies (no cutoff, "lectro-stop" brakes on a steam engine, can't shovel coal or water the engine, etc.).

Sometimes you just have to find a nice enginespec and replace the KUIDs in the loco's config file.

I understand that physics may be different in Cab mode, so just to test it, I went and took an engine and ONLY an engine, the F40PH locomotive, and tried to see how fast it would go, and it would only go 122km/h not pulling anything, while I can get it to 160 in DCC.

I don't think 160 is an unrealistic goal for an F40PH engine, as they use them all the time in Canada to pull VIA rail trains, as well as in the US with Amtrak.

Is there something I can do so that the engine will get to 160km/h? I know about the enginespec file that can be tweaked, I did that, and after doubling the maxspeed value in the spec file, the engine did not go any faster in cab mode, still topping out at 122km/h.....any ideas?

I'm running a passenger route, similar to the VIA/Amtrak trains, and 122 is pretty slow for these trains, which I have clocked myself in person at 167km/h, so phyiscally it should be possible.

Any help is appreciated.

Thanks

You could try editing the enginespec file. The right hand column in the throttle-power container is acceleration at the speeds listed in the left column. So, for throttle position 8, increase the acceleration values by 160/122 or 1.3 to see if the top speed in max throttle changes. If that's not right, adjust accordingly.

Thanks for the tip, I tried to edit the engine spec file, but the numbers confuse me a little bit, I know the 6 is throttle notch 6, but the rest of them, as per your comment, the "375" should indicate speed, but does the train go 375?? that seems too fast....I'm not sure what they mean or where to even start editing.

6
{
0 "375"
2.2 "300"
4.4 "250"
6.6 "150"
8.8 "120"
13.3 "80"
22.2 "41"
31.0 "0"

The first number is the speed in meters per second. The second number is the traction effort at that speed (don't know the units). A value of zero for the second number means 'no more accelleration' (top speed).

May be in kilonewtons?
I don't like to use the last line with 0 Sometimes it makes train behavior unrealistic.

Once you have Raildriver, you do not want to run trains without it...
