that what I thought thanks rambo1..
The holes are probably for items that other road names would have used on their cabooses that SP did not.
I bought the sp model c 50 9 made by athearn there are holes next to the battery box am I missing parts or are the holes just left there? would they athearn have not plugged them? Anyone out there have the same or similar model no4742 that a look.thanks rambo1..
