Having been a Electric Train repair Man for over 63+years this is the Top of the line. Both this switcher and the Classic Hudson. The plastic trains (made in China) are JUNK. You cannot get PARTS that will not work or unable to replace or repair. When Gilbert came out with the 0-6-0 Switcher or the 4-6-4 Hudson they made them to last. The smoke units work PERFECT and require little or no service . On the switcher , It did not come with a bulb in the boiler front. All my 0-6-0 .that I sell, have a lighted boiler front.IT HAS A EXCELLENT WORKING SMOKE UNIT . WHO LIKES WHITE PAINT WHERE A BULB COULD BE.  If you are lucky to own the switcher, I have them listed also. The Number on the Locomotive is155. I check every LOCOMOTIVE that I ship out. ALWAYS OPERATE YOUR LOCOMOTIVE ( if made in China ) ,SLOW . IF THE NUMBERS ARE HARD TO READ OR GONE, I MAY ADD MY OWN.
