Regards the Atlas, BLMA, and Trainworx piggyback flats, do the bridgeplates attach by snapping in or do they need to be glued? I know that the later versions of these cars didn't have them, but my era is the mid 60's to late 70's......any advice? Tim
The Trainworx bridge plates are similar to the Micro-Trains ones, they snap in and are positionable. The BLMA bridge plates are glued in place, and break off easily, as you might imagine, they are not positionable. Don't know about the Atlas cars, I don't own any. For what it's worth, I'm not big on N scale freight cars being glued together, I prefer the engineering to allow for snap fit assembly.
The Atlas bridgeplates come as separate parts that must be glued in place and are not adjustable. Note that depending on your modeling era you may not want to install them. On earlier runs you also had to modify the bubble packaging if you wanted to put them into the box after adding the plates, but on at least some of the later runs they fixed this.
