My layout, The Great Plains Northern Terminal Railroad, will be on tour 
on the evening of  Dec 5th and the afternoon of the 6th.  I'm the only S 
layout this year--my Sn3 friend decided to take the year off.  So if 
your off the beaten path in the Houston area stop by for a visit. 

To that end, last night after the pumpkin pie, I started my annual wheel 
cleaning ceremony.  I finished most of my main freight yard and several 
nearby sidings.  I've come to the conclusion that the wheels that seem 
to stay the cleanest are the silver plated wheels, followed by certain 
recent SHS wheel sets.  Most of my wheel sets are NWSL and SHS blackened 
brass wheels.  Most of them need a fair amount of cleaning.  Some of the 
SHS wheels have a glossy finish and they do seem to stay cleaner.  The 
silver finished wheel sets are either imports or earlier shiny NWSL 
wheels. 

Although I'm no expert, I would assume the plating or glossy surface is 
the help here.  Where the blackened wheel sets generally have a dull 
surface it must attract and hold the dirt.  This does bring up a 
question!  If dust is generally a light gray color and the 
oils/trackcleaning products are yellowish to clear--why is the dirt on 
wheels black?  So if we've figured out how to load a hopper with broken 
glass put your minds to this one!
