Bachmann Goose #1 surging, any fix?

Modeling Motive Power

I’m going to be working on my Bachmann Goose #1 this summer. Is there any fix for the downgrade surging?

By Goose, do you mean the Railtruck? If so, check out George Schreyer’s site:

George Schreyer address this problem on his web page.

All of the above… + the “procedure” as he was encouraged to call it was developed by TOC:

I did the fix on mine and it helped a bunch, but still had minimal surge

Thanks for these links.

I was aware of the screw change out to protect from excessive gear wear. But I was wondering if anyone has come up with a way to eliminate the grade surging. From the links posted it doesn’t look like a fix has been developed yet.

So she’ll surge. I’ll say the driver has trouble shifting gears.

Matt,

Geo. Schreyer says it does work. Didn’t you watch his clip?

The clip wouldn’t open for me. I think my adblocker and cookie blocker might be preventing the quicktime video from opening.

I’m also a bit hesitant to add drag to the Goose since I run it on a small battery. But if this is the easiest fix I’ll give it a try.

Update, got the clip to work. Was my adblocker (http://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-embarassed.gif)

How steep is your grade? Mine is near 5% in spots and everything I own from Bachmann surges on the steep parts. I figure it can’t be helped. Technically is has to do with the gear design & tolerances. Not something I have the expertise to correct.

About 2% to 2.5% at the steepest.

#10

Well that shouldn’t be a big problem then.

#11

Matt,

Geo. Schreyer stated that his grade was 4% and the drag he added fixed his surge.

#12

I did the drag fix for someone’s railtruck and while it did work it cut it’s battery life almost in half.

I believe George Schreyer runs track power, so it wasn’t an issue for him.

He runs DCC… even better than just track power. (http://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-tongue-out.gif)

Maybe is Revulsion and better than dcc?

Drag is a bad thing with on-board power. I did all sorts of stuff…tried a new driveshaft with tubing instead of their loosie-goosie u-joints. Not worth the effort.
