4-8-4 GS4 streamlined SP Daylight steam loco & tender w/DCC

[RR Bear]

has anyone had experience with this Loco?

i just bought it and am having major problems getting it to run.  for the first 30 minutes of the usual break-in routine, it jerked, started and stopped as if it were losing contact with the rails (which were clean).  that seemed to work itself out somewhat on straight portions of the track, but when the engine goes into even the slightest curve, it stops.

the only consistency is that when it stops, it will start again if i gently nudge one or the other of the sides of the Loco.  the problem persists even after 2 hours of running.

am i doing something wrong?  i've re-cleaned the wheels AND track with no positive result.

none of my other locos show any such problem on the same track

HELP!  :>)

check the contacts.

What is the radius?

[RR Bear]

the radius is somewhere between 30-36 i think.

[Santa Fe buff]

That will bearly make it on 20 radii.

[SteamGene]

That is a big "about" for an HO radius.

I am having trouble with the front trucks staying on the track. Got most of the problem fixed by sanding the rail to smooth sheen. but the beast still jumps the track and puts the computer on the fritz........

RR Bear and late model Folke-Wulfe high altitude interceptor - are the same person?

After spending a good portion of the afternoon trying to examine the problem with this 4-8-4, i came to the conclusion that Bachmann should consider using a small chain as a drawbar for this particular engine, or perhaps a more elegant solution of using ball sockets, as in aircraft, for motion in three dimension. just a thought.

Are you running it on DC ? - It is DCC on Board -

If DC you have to remove the Tender Shell - Remove the decoder and install dummy plugs (2).  Look on the bottom of the tender assembly page it shows how to install plugs
