Was Google surfing around Hugoton, KS this morning.  Noted this interesting pair of dedicated flatcars.  The large containers say "Haliburton" so I wonder if they're oil drilling "mud" transporters.

In the same town at that time was a privately owned (SFGX) GP7 loco and slug on a grain siding.

Hello, I'm new here, it looks like this is the place to be. There is lots of info on this forum!

I currently building a triple deck HO scale layout, based on Union Pacific's line from Las Vegas to Yermo Californa. Just wondering if anyone knows the name of that subdivision? 

Thank you in advance!

Mike.

I know just about any type of car can show up at a team track sooner or later. But how common was it for covered hoppers to be unloaded at a team track in the mid 60's? What kind of offline industry would be using a team track in this way? What would have been the typical kind of load going in or out? And how would the hopper have been loaded or unloaded? 

On a similar note, were covered hoppers carrying plastic pellets yet in the mid 60's? Say for an offline plastics plant?

Thanks!

I realize this probably varied by railroad but typically what would the proper placement of particular types of passenger cars be in a passenger train and why?
