Loco derailing - Bachman Spectrum 460


 

Greetings and happy holidays to all.


I have a Bachman Spectrum 4-6-0 that runs very well otherwise, but the pilot truck tends to derail on a certain?segment of my handlaid 18" radius track.? All of my other equipment, including a Spectrum 4-4-0, ?runs just fine on this section.? I have re-gauged and re-spiked several times but this engine pilot truck keeps jumping off.


I checked the pilot wheelsets with my NMRA gauge, OK.??


Any suggestions for fixing the problem?? Should I add weight to the pilot truck??


Thanks in advance!

Check wheel gauge, might be "wide", would work on straight track.
Make sure wheels are square and true on axle. Keep us posted.?

Usually pilot trucks have a spring of some sort to help push them down onto the track.? Look at your 4-4-0 to see what the difference might be.? They probably should be similar.

Fred,
By all means try adding some weight, you have nothing to loose and you will most likely fix the problem. Put it on with a tiny amount of glue first in case it doesn't work. Good luck and happy holidays.

I'll drop my 2 cents worth ? Two things to look at [more] ? Does it derail at the same spot every time ? Within a close call either direction
? If so , check the curve for proper radius , if it slips out of alignment [?] that will cause problems ?? Springing of that front truck can cause problems , and not all the time either . Go to hoseeker.org for literature , parts breakdowns for your loco , or OEM ??? Henry H.

I forgot to include change the direction of travel for all involved ?? If it does it again , same area . then it's the track ?? Henry H?


 

Try making a radius checking tool ?? You might have a ''kink'' in that spot ? Run that loco through that curve in the other direction . If it derails there ? Then the cyuve is out of radius ?? Henry H.
