For some 50 years now, their familiar rail inspection cars have barnstormed over railroads large and small. Inside these self-propelled cars (many of which are rebuilt gas electric "doodlebugs"), special equipment ultrasonically tests each rail for hidden defects that could cause serious problems.
 
Now, you can add this vital operation to your HO Scale railroad with Walthers all-new models. Fully assembled and ready for service, the cars are driven by a flywheel-equipped power truck and wired for 8-wheel electrical pickup to run smoothly at any speed. A styrene body captures the details and features wire grab irons for more realism. There's also a detailed interior and authentic trucks that simulate the special testing equipment. Classic yellow paint jobs spanning the past 50 years and super-sharp graphics make these cars stand out whenever they roll across your layout. Running at reduced speeds, usually 10 mph or less, they're a fun addition that will make any operating session more challenging.
