I have 50+ of these from a yard sale. I know similar things are used on semi trailers to to show that they have not been opened before delivery. What would the UP have called them and what is/was the use? On TOFC trailers, on containers, on other rolling stock? Could even be on switchstands etc., I suppose. any ideas or info.?

The NYCHS promoted a NYC 19000 series wood caboose a few years ago to be made by Tru-Line.  I have heard from different sources in the hobby manufacturing "world" for various reasons this project most likely will not be done.  So now I am stuck with two options, scour Ebay and other sites to fine the Trix Model (at most likely prices of over $100 a car) or built one myself.  I am debating is it feasible to perhaps design the underframe and roof's to be done by Shapeways and the walls and cupola out of basswood or taskboard.  This would be for HO Scale

Hello all,

I'd like to replace the fans on my P2K SD9 and GP9's but I'm having trouble knowing which ones would be appropriate. I do' not see a correct replacement from Canon and company listed. Which 36 and 48 would work for mid 70's GRIP program 9E/R's?

Also referencing the picture in the link below there is an odd flat top 36" fan on the rear of this GP9. What would be appropriate?

When, if ever, might you see a freight car with trucks that don't match?  i'd assume that, after a wreck, whatever can be put on to roll the car away would be done--but would they ever be left mismatched?  I was wondering for two reasons...

1.  I have a couple of mismatched trucks lying around; their mates met bad ends

2.  If it would be done in reality, I might do a car that way to creat an interesting model...perhaps also have most of the car well weatehred, with a small section looking brand new...
