Princess Hank gave the OK. The EMD E6 was a 2000 HP locomotive achieved by using two 1000 HP diesel engines. It was produced from 1940 to 1942 (production was stopped due to WWII). It was perhaps GM’s first truly successful locomotive. The E6 was a A1A-A1A configuration. That is for each of the two trucks, a powered axle, an unpowered axle and a powered axle.
Two examples survive. One is at the Kentucky Railway Museum. That one is an A unit being a former L&N locomotive. My model is an A and B unit from the Southern Railway. Two units slaved together at a total of 4000 HP. It is a Proto 2000 Life-Like model. This is one of their higher end models. Life-Like is normally known for “toys”. But their Proto 2000 models are indeed not toys.
