Talltim Posted January 6, 2015 Share Posted January 6, 2015 How long is your typical 4 bolt fish plate? Full size or scale dimension Link to post Share on other sites More sharing options...
highpeak Posted January 6, 2015 Share Posted January 6, 2015 Trattman (1926 edition of "Railway Track and Maintenance") noted that there was "great diversity of practice" but that the general practice in the 20s was towards short splice bars with four closely spaced bolts. The NYC used 6 bolt bars that were 38" long. The DL&W and LV used six bolt bars that were 27 and 26 inches respectively, while the CNW and PRR used four bolt bars that were 26 and 24 inches long.

dave1905 Posted January 6, 2015 Share Posted January 6, 2015 Go to this link on the UP website: http://www.up.com/customers/ind-dev/operations/specs/track/index.htm Scroll down to track material, then Std. Dwg 0904 - Joint bars and there is a pdf drawing of 24, 28 and 36 in joint bars that will give you spacing and hole patterns (there are 4 shown) and a table for rail sizes from 110 lb rail up to 141 lb rail.

highpeak Posted January 6, 2015 Share Posted January 6, 2015 A quick check of the Details West plastic bars against the data linked to by Dave shows that the 6 bolt bar is pretty much spot on. It's pretty easy to shorten them to a 4 bolt bar if that's appropriate. I like the plastic ones because there is more relief to the detail, the etched offerings are too flat. Possible the plastic detail is a bit overscale, but pictures of track show the bars as being quite noticeable. The D-W offering does not include the easement shown in the UP drawings, so better give it a quick swipe with a file if you need that before the track inspectors show up.

Talltim Posted January 6, 2015 Author Share Posted January 6, 2015 I'd realised that they were shaped to fit into the web of the rail, but not that some were hollow at the back. Link to post Share on other sites More sharing options...
dave1905 Posted January 6, 2015 Share Posted January 6, 2015 This all assumes that you are modeling 100 lb + rail. If you are modeling 90lb rail or less the joint bars, angle bars are shaped completely different, they are actually an angle that fits against the web and the base of the rail Link to post Share on other sites More sharing options...
