Williams GG1 PS2 matches MTH GP9 speed!

Nearly all DCS engines seem to be factory set to pretty well match each other for speed.

 

I have run many many long long trains with a variety of mixed power steam various diesel types and they have always matched and worked just fine together for long trains with head and tail end power + mid train power at different locations in the train.

 

DCS great design for matching speed as designed by MTH.

I repeated the experiment at Higer speeds after factory resets on all engines. Diesels are 8ish percent faster. I will figure it out?

Remember that sound files are made for MTH locos, which may or may not have different gear ratios and wheel diameters than Williams.  You'd have to start producing your own tach tapes with differing spacing.

Thanks

While I mention the Williams unit, it actually matches my MTH GP9, being less than 1%faster, after factory resetting all the engines. The issue is my MTH steamers match each other at 9% slower, than the diesels.

 

I'm going to send the Berk out for service in January. If it comes back matching the gp9, I will address the 2-8-0.

 

One would think move on, but the GP9 BELONGS on the head of my Pennsylvania passenger consist. The Rudolph 2-8-0 looks silly, not pulling Christmas cars, even to lotus rails. Not to mention, I just put passenger sounds in the gp9

I'd venture a guess that the wrong sound file may be loaded.  I know there are differences in the gear ratios in some sound files, that may be what's happening here.  I have a number of MTH steamers and diesels, and they all seem to track very closely at scale MPH.

John,

I factory reset them all. The 2-8-0 has the Rudolph sound file. The GP9 has the only GP9 passenger file, I could find (which is different than what it had at the beginning of the experiment) and the Berk has never been reloaded... I will hopefully join a club this year. (It's a goal every year). For now the GG1 is pulling more cars, than I had hoped for (23 and adding occasionally). No need for double head. Rudolph goes in the box (nephew/niece pending.) 

Is the GP9 file a Railking or Premier file? 

Premiere. The loco is a ps1 premier, with a ps2 upgrade. I see where you are headed.

You'd think that would work, hard to say why it's different.  The other wild card is the flywheel size vs. the strip you used.  If you have the wrong stripe count, that'll throw it way off.

 

I have a micrometer. I want to say I used  it.... I will measure and see if I have the correct size available, from the gg1 kit.

The flywheel stripe count can really throw off the speed!  There are 24 stripes on the flywheel tapes of any size, so if you look at the motor and count them, less than 24 will make the speed considerably faster.  If you had 22, for instance, it would be about 8% faster.  Each missing stripe would add a bit over 4% to the speed.
