Can you comment on high-sided versus low sided gondolas, and what applications would require use of each type? I am sure that weight is the over-riding factor, which would lead me to believe that the Grimmel's material is "light"
I'm no big expert on this car type, so others, jump in to correct me if need be. To your point, car size is commodity density-related. Gons for scrap steel have traditionally been ~55' with 5' sides; "mill" gons are 65' with similar side heights, and are used more for structural steel, coils, etc. Two things have been changing the landscape - the advent of 286k gross weight loading and new loading rules that prohibit product from being mounded above the height of the car sides. Both translate into the need for higher cubic capacity, i.e., longer length and higher walls.
Ok, why I don't understand Grimmel's move to get cars, and these cars in particular:
Size: Grimmel's cars are 60' (interior length), 9' 5" high sides, 6,800 cu ft, 82,800 lbs tare, 286k gwl... in other words, a big mother of a gon. First of all, to the best of my knowledge, that line (and connecting lines) are, and will remain restricted to 263k gwl. Secondly, Grimmel's ships ASR, no? The optimal material density for these cars is ~30 lbs/cu ft. Scrap steel is in the 50-75lbs/cu ft range and I believe ASR is close to that, no? If I'm right, why would they need such a high cap'y car?
Car supply: Along the lines of the old adage, "why buy a cow when you can get the milk for free..." Ok, no car is "free," but there is not exactly a gondola shortage. Perhaps they wanted cars built to their exact spec, but why buy new equipment when there's soooo much surplus equipment available in the market (then again, based on the cars' build date, the order may have been placed prior to the the bottom falling out of the market when car supply was tighter, but still...). If PAR wouldn't supply, there must have been leasing alternatives. Then again, maybe these cars are triple net leased or some such arrangement - which could explain their "personal" reporting mark. But net leasing a small fleet is an administrative hassle. Does Grimmel's ship from other, non-PAR locations???
Again, I might be all wet, but on the face of it, it doesn't seem to make sense.
