[quote]QUOTE: <i>Originally posted by railroad65</i> <br /><br />Didn't SOUTHERN RAILWAY have a multi-unit coal car back in 60's. What happened to it? Same as Trough train? <br /> <br />Railroad65 <br />[/quote] <br /> <br />You're refering to the Southern 100..... <br /> <br />http://southern.railfan.net/ties/1965/65-8/toc.html <br /> <br />.....a four unit car using single axle bogies on each unit with 38" wheels, aluminum body with center sill, and link pin connections between units. Years ahead of it's time, it's load factor was a whopping 7 to 1! The problems with it (again from memory) aside form the specialized components, was that the link pin connections between the units made it a pull over risk on curves. Replace the link pins with rotary drawbars between the units, beef up the single axle bogies with greater suspension, and get rid of the centersill using side sills instead, and you've got a car that would pay big dividends today. <br /> <br />Comparing the Southern 100 to the Trough Train, the Trough Train was much lengthier between coupler ends, and was not adaptable to rotary usage (unless some coal plant wants to install a 300' long tipper). The Trough Train used articulated two axle bogies between units compared to the separate single axle bogies of the 100.
