b17 barnsley

[alan_quinton]

when i run this engine it slows down or stops on curves.no other engine does this, but just come to mind i sent b17 selbey hall back for same reason.any ideas?

What radius curves do you have?

[Bigskybirds]

I recently had two B17's from Hatton's both had to be returned. They slowed on 3rd radius curves. 

Hattons agreed there was an issue and gave me a full refund. 

[alan_quinton]

What radius curves do you have?

 

[alan_quinton]

i have fourth radius curves. i have 2 more b17 and they are ok

[walkingthedog]

OK we know the curves aren't too tight then.

Could be the wipers coming away from the wheels.

 Wouldn't the wipers coming away from the wheels be like slamming on the rakes rather than slowing to  halt (I know one of my locos with this problem just stops abruptly. Unless of course this loco has some kind of current storage on board

Do the wheels stop completely or do they just fail to grip the track?

My B17 Barnsley also slows down on curves and slightly uneven track - however, it's a traction problem not an electrical one.  The front bogie seems to have no vertical play at all, and if there is even the slightest of inclines (I'm talking about going from dead flat to a rise of about 1 mm over the lenght of an R600 single straight) it lifts the front and middle driving wheels off the track.  Thus only the rear driving wheels are getting an grip on the rails.  The wheels spin happily but there's no movement of the train - it struggles with 2 or more pullman coaches in those situations.  With pickups on the tender wheels there is no problem getting electricity to the motor.

I haven't got around to adjusting the front bogie yet but I am certain that this is the solution (in my case, at least).

@alan_quinton.........the back to back wheel measurement is important.........if the middle axle does not have enough tolerance then it won't get round curves easily.........need a vernier gauge to check.......HB

Both of my B17's would slip once a coach was attached. I sent a video to Hattons they were aware there was a problem and immediately offered a refund.

 The B17 models I had with this issue were both Gilwell Park, there must be some sort of production issue and although I want to get a B17 I decided if Hattons knew of a problem it was probably best to leave that model alone. They described it as a drive problem.

My B17 goes round my 2nd rad curves OK and has no probs with 3rd rad curves. It pulls up to 5 coaches with out wheel slip. It sometimes does not like 5 Pullman's and Slip's a little but usually runs ok

A UPDATE ON MY PROBLEM WITH MY B17,I HAD 2 B17,S SO I DECIDED TO SWOP THE BODYS OVER,AND IT SEEM TO HAVE CURED THE PROBLEM  

[Bigskybirds]

 Third time lucky for me I ordered another B17 Gilwell Park again from Hattons and that runs fine.

[The Doc]

The problem with My B17 Barnsley, as stated earlier, was the lack of vertical movement in the front bogie, lifting the front driving wheels off the track.  I've taken the bogie and T-shaped mount off the model (very easy job with a small Phillips screwdriver) and took the screw out that mounted the bogie to the T shape.  Theres a spring to help keep the bogie pressed down on the track, and what looked like a clear plastic washer that was preventing any upward movement of the bogie.  On closer inspection it was two identical washers, one on top of the other.  I suspect that someone in the factory has been using two washers (perhaps accidentally?) where only one was needed.  I reattached everything and now my loco runs perfectly, hauling 5 Hornby Gresleys around my layout (including 3rd and 4th radius curves, and the odd bit of uneven track) without any slipping - previously it would slow down with 2-3, and struggle to start in some places).  A great improvement on previous tractive effort.  It is also running more smoothly as all the driving wheels are picking up electricity consistently, rather than just the rear ones.
