Reply to "Questions about 21" K-Line passenger cars"

2 of them are 21” and the others are 18”

other then length there are little differences

My friends also have mostly 21 “ and they were the ones whom hooked me on the k line passenger cars.   They look and run great  

Quickly snapped a shot of one of my 21” k line.  One of my favorites

I personally want a couple more lines but my budget says not now.
