Unresolved problems

[mojo]

After having left running trains on my not quite finished layout for some time whilst doing scenery etc., I decided to have a play!
One of my U.M.locos has decided it does not like to traverse a particular turnout and comes to a full stop when going forward but will smoothly glide over it when running tender first. Previously it caused no such problem at all and no alterations to either loco or track have been carried out.
So maddening!

Hi ,
If no other loco has problems traversing then yep loco specific, if it is an insul frog then when loco stalls check wheels on metal rails on side with wheel stopped on frog - this one picks up ok others have ceased. worth a quick check for static grass or other gunge on pickups.

Hope that helps ! I got off e-bxx in last couple of months several non runners where bogie stuffed to jamming point with grease and grass ! 15 minutes cleaning and all happy !  Pair central 150 non runners less than that with bending a motor pickup strip. Keeps me happy mending stuff..

Have you tried giving the point in question a thorough clean. Insulfrogs especially will collect "gunk" easily and this could cause your problem. Try to make sure that the point in question is thoroughly clean.

The point in question is elecrofrog and no other loco is affected, so I took off the front bogie ( a B12 loco) and it went through both ways fine.
Refitted the bogie without alteration and the problem has disappeared!
Weird!

Hi ,
good to know- might be a case of the bogie lifting front end slightly and losing pickup. Refitting has ajusted ride height - screw a fraction of a turn less perhaps.

Just love it when the gremlins get bored and go elsewhere!

In my experience, as often as not, this is the difference between success and failure
