Can anyone tell me how much spacing should be allowed between wheels and rails around a track? I seem have some space between mine when I move my trucks from side to side on the rail.
 
Hi skiddgreen, the rolling stock have set wheels.
But when I have to regauge a diesel I simply turn it upside down in my hand and use a jewelers driver carefully prise one wheel on each bogie a little to widen the gauge or visa versa if to wide.:)
See if that solves the diesel prob, They do need a little play so dont make it a tight fit on the track.
 
Whoa up one here! There is some built in side to side play in the trucks of the cars and locomotive even when in proper guage.This side play helps the trucks track better by allowing for changes in track such as switches,curves and unseen track imperfections.
 
I think most rolling stock and locomotives are manufactured in gauge other than the cheap toys, but Athearn locomotive wheel sets will tend to be out of gauge. If you have an NMRA standards gauge, you can easily adjust Athearn wheel sets by using your thumbs on wheels on either side and working them back and forth until the wheels are in gauge.
 
You have to be careful re-gauging wheels. I redid a 6 wheel (British) truck and then had trouble getting it through my Peco double slip switches. If you make the wheels too wide, they can go down switch frogs the wrong way.
