I doubt there is much secrecy about either BNSF or UP's LNG/Diesel programs as both projects are long dead. Both TRAINS and EXTRA 2200 SOUTH ran articles about this at the time(1997-98). Essentially the problem was one of converting a conventional Diesel engine to run on a mixture of LNG and diesel fuel. The latter was necessary because natural gas will not easily ignite in a compression engine, so the diesel fuel served as the ignitor. The ratio was something like 90% gas to 10% diesel. In order to acheive this efficiently the Diesel engine cylinder heads would have had to be completely redesigned. The most successful locomotive design to use LNG was the MK/Boise Locomotive MP1200G. This uses a caterpillar 3516G engine which has a spark plug ignition system designed from the outset to burn natural gas.
