Recent posts and e-mails have got my thinking about the order in which you secure a passenger train. If it is not a matched set issued by the supplier, do you go after the passenger cars first and then seek corresponding pulling power, or do you reverse the process. Some suppliers may catalog matching engines separately from the cars, but they may or may not be prototypical. I have strong feeling about this. My experience tells me that it is much more difficult to find the passenger cars, so I look for them first. This is particularly true when you are seeking sets that were retired and not currently available from the original supplier. I do not worry about pulling power as typically there are many options out there.
How about you. Do you go after the passenger cars first, or do you want engines in hand first. It will be interesting to learn what the majority of you do.
