Question about editing bogey movement in D/E locos.

[JonMyrlennBailey]

I have been customizing (kitbashing, if you will) a certain "aftermarket" (non-built-in/DLS-acquired) diesel locomotive <kuid:568725:100047> "CF7 Locomotive Amtrak Ver. 3" by jregner1955 lately in config. Giving her a new hornsound from the ATSF F7 loco, modifying her smoke behavior, lowering the bogeys a tad to look as if her wheels are more solidly touching the track rail tops, editing out cab sway (a TANE-exclusive behavior) altogether by adding these tags and corresponding values [suspension-pitch-limit,0....suspension-roll-limit,0] and just happened to notice these parameters in the file as follows:



bogeys
{
0
{
bogey <kuid:186817:100066>
reversed 0
rotation-permitted 0
sideplay-permitted 0
}

1
{
bogey <kuid:186817:100066>
reversed 0
rotation-permitted 0
sideplay-permitted 0
}


By default, rotation and sideplay of trucks WERE not permitted on this particular engine because the tags were set to 0, zero.

I figured the ROTATION had to do with the natural pivot of the trucks as the engine goes round turns. I test drove the engine and observed the trucks closely. Just as I had suspected, the trucks did not turn independently of the loco body as they should so I changed the rotation value from 0 to 1 and then that fixed that: the trucks pivoted in turns and the cars were following the engine more naturally in turns too, no longer jumping laterally at the couplers as before.

I was wondering about the sideplay values of the trucks. Should I leave that alone or set it to a 1 also?
Is there a reason not to permit sideplay?

Is there a reason the author of the loco "locked" the bogeys in place so they didn't turn or steer through curved track originally?

PS - Isn't it also customary for bogeys to be reversed (so the direction of the rear truck is opposite the direction of the front truck) as is the case with most GM/EMD locomotives?

Yes ... You should leave it alone, unless you like breaking things
Yes ... You should not attempt fix it, if it not broken
Yes ... Yes ... He dint' know how to animate it
Yes ... Yes it is

Electric engines are weak and not pretty. That's why I de-electrified my clone of Avery-Drexel by ripping out all the catenary poles and wires (except those catenary objects that were built into the mesh of two of the route's TUME-designed bridges and apparently not easily removed, I made those bridges with a RR worker scenario as if the catenary equipment on those bridges were about to be removed as the final phase of the de-electrification) and putting the yellow Little Joe on display surrounded by fencing in the town of Avery. I like loud, smoky, smelly combustible-fuel-driven machinery.

For all those "jumping ship" --v

Are you serious? Diesels have only caught up in the past couple decades to what electrics could do 100 years agom

Yup...

He's being prototypical though. Before the MILW discontinued the route, they had gone to diesels by then, except they were big diesel-guzzling SD40s and GE U-Boats.

Once he's done, he'll then rip the track up and turn it all into a dirt path and sell off parts to a rail trail.

I am not even sure if the real MILW left the electrification equipment intact on their road by the time they completely dieselized or pulled the poles and catenary wire out before the line finally closed down for good. Just for fun, though MY Avery-Drexel is mostly diesel, I will still have at least one steam excursion train on MY line too. There is one tunnel on my line longer than a (scale) mile. I hope it has good ventilation fans. Sometimes tunnel doors are also used. That might be a cool Trainz asset creation idea: auto-operating tunnel doors and fans.

They pulled it. GE offered to give them all new locomotives and a rebuild of the electrical system so they could demonstrate their electric technology to the rest of the railroads. MILW preferred to look at the scrap value of all that copper.
