What are the odds that different manufacturers will select the same engine number for the same type locomotives.
I collect the Missouri Pacific road name.
Lionel makes a Mopac GP35, road number 603, 611non powered and 607.
Atlas makes a Mopac GP35, road number 603 non powered, 611 and 618.
MTH makes a Mopac F3 set, road number 515, 516 and unnumbered B unit.
Atlas makes a Mopac F3, road numbers 513, 514,515, 516 , 513B, 514B, 515B and 516B
Not really paying attention to this, I have two F3's in the same number. 515 and 516.
I guess it would pay to investigate a little more when you want the same unit from different manufacturers without the same road number.
I can see that a manufacture could lose out on a sale because they have the same number as another manufacturer.
I would not buy a Lionel GP35 except the one number that I may not have, (I have the Atlas 603, 611).
Just thought it was odd that there were so many engines in the same road number and this is in just one road name!
