The first car I purchased was an Exactrail Trinity 6275 Boxcar. I actually owned one of these already and I absolutely loved it. I wanted another for years, but Exactrail had sold out of stock completely and second hand models were going for ungodly amounts of money on eBay. I held off buying one for many years hoping that Exactrail would re-release the car and Thankfully they did! I snatched one up as quickly as possible (which was a good idea because they sold out again in an insanely short amount of time) and now it sits on display next to my original car. Both are waiting patiently for me to get around to weathering them.
The freight car was advertised on Ebay as "New in Box" and in classic Ebay fashion, It arrived as anything but. The axels were broken off, handrails were busted, coupler boxes were missing, etc. I am glad to have it as part of my collection, but it will need quite a bit of work to get it back in shape.
Both of these freight cars are special to me though as both of them are cars I never expected I'd one day acquire. It just goes to show that good things come to those who wait!
