Re: Are there Articulated Oil Tank Cars?

There is not a good reason to have articulated rail cars, unless, the lading is unusually light. The reason that certain types of cars may be articulated is that their loads (containers, automobiles, even grain) are relatively light. But the contents of tank cars are generally relatively heavy.

The direction that tank cars are moving is to heavier cars, a la 286K style cars. Here's a relevant article:

Here’s the point: If you follow the changes in railcar design over the past 20 years, there are two very significant design changes that have impacted railcars, their manufacture, and their financing. One is the increase in gross rail load to 286,000 pounds. The second is the shift to a specifically designed railcar truck to haul that increase in capacity, the AAR S-286 truck design. The S-286 design was officially implemented in 2005. Any tank railcar built with a railcar truck that does not meet the S-286 spec will not be able to meet the criteria for hauling all commodities at 286,000 pounds capacity whether or not it meets the other design criteria.
