Ah, an ex-Reading Company Silverliner IV married pair.
I wish models of these and the Jersey Arrows were more readily available. I do have an IHP Silverliner IV married pair kit (though its missing floors and trucks), but as i understand it, few of those models were made. I do have a ton of the "single" Silverliner IVs, but some pairs would be nice.
Island Model Works makes a more modern version of the cars, but they don't really look consistent enough with the IHP cars to be put in the same consist.
