BLI Hudson iratic performance
Posted by Tophias on Saturday, February 10, 2018 8:21 PM

I’ve been a forum member for about 4 years now.  I’ve asked many questions and received many very helpful, useful answers.  I have always been very appreciative for all your help.  So now I would like to make a contribution, trivial as it may be.  3 years ago I purchased a BLI Hudson which ran well at first.  But after about 6 months it started running iratically, and has done that ever since.  I cleaned all tender wheels, loco drivers, track, tender wipers, everything I could think of.  Even bent the wipers closer to the axles.  All the while, when it stalled, a very light touch of the tender brought it to life.  So I thought maybe the harness was not inserted fully and fiddled with that several times. No change.  So I kept thinking of the light pressure on the tender, and then the “light dawns on Marblehead”.  I took the tender body off and added about 1 1/2 - 2 ounces of weight, and voila, it now runs consistently.  So if anyone out there has a similar issue, try adding weight (I used those 1/4 ounce weights) to the tender.  I hope this might help at least one member with a similar issue.

Thanks for sharing your experience. It is sometimes these seemingly simple solutions that at first may not be obvious but can alleviate headaches.

Thanks Tophias!

I have quite a few BLI steam locomotives in my roster and I will certainly look into added tender weight. In fact I recently lifted my B&O P-7 Pacific off the layout to do a traction tire replacement and the thought crossed my mind that the tender sure did feel light. I didn't make any changes to it though. I'll re-think that.

A couple of my PRR H10s have shown what you describe that they will freeze, then a light tap will get them moving again. 

I believe a tiny drop of CRC 2-26 or, better yet, D series Deoxit really helps with electrical contact at pins, wipers and sockets, too.

Thanks for your contribution,

Regards, Ed

I had the "too light tender" problem on a Spectrum 4-8-2. I had to remove the large floor weight to create a space for a 1" speaker when adding a sound decoder. Without the weight, the engine kept losing track connection. Similar to your story, adding the 1/4" sq. lead weights wherever I could squeeze them in solved the issue.

I have watched the Bachmann forums for some years and adding weight to the tender is a common solution.

Some years ago I coupled a Bachmann short USRA tender to a Mantua 0-6-0 and put wipers on all the wheels and had to add weight also.
