That's an interesting question -- and Marmon also owns Union Tank Car.
From what I know of competition law, neither is going to be a serious problem. There is no incentive for Railserve to deny its in-plant switching services to companies using a different class I than BNSF, and there is no incentive for BNSF to browbeat companies to use Railserve. Similarly, there is no incentive for Union Tank Car to stop selling to companies other than BNSF.
There *might* be some incentive for BNSF to buy preferentially from Union Tank Car, so we might see a condition on the deal requiring BNSF to subject its leasing, purchase, and maintenance of tank cars (and other rail vehicle products manufactured by Marmon) to competitive bidding. Given Buffett's method of conglomerate operations (encouraging each company to operate independently), I expect this would be agreed to without a blink.
