my ESPEE MODELERS ARCHIVE
California's Railroad to the U.S. 1861 - 1996
Southern Pacific U50
3 units delivered
SP bought only 3 of these double-engined monsters, and never went back for another order. These were the first U50 model, that rode on 4 span bolstered B trucks. Similar units went to the Union Pacific, and they subsequently bought the U50C model.
To clear up a point, these are correctly called U50's, as they were the first, it is wrong to call them U50B's or U50D's.
Each of the two engines provided power to only two of the B trucks, and could be operated independently. They were never totally successful, one reason being the loss of 5000hp should one engine die, then the whole loco had to be taken out of service to be repaired. If that were two locos of 2500hp, and one died, you would only lose 2500hp, ie one unit not both. The U50's were also among the first units placed in storage, in times of power surplus'.
On the SP they gained the nickname 'Baby Huey's' from the cartoon character of the same name.
As you can see the list of References is rather slim, so I'll add these:
