I recently was given a N Scale Diesel Engine that was minus the Couplers.My problem is I cannot identify the Engine.
To me it looks like a EMD SD-45 however the walkway platforms both in front and rear of the engine are extended.
The fuel tank is embossed with Spectrum By Bachmann China.the Roadname  is Southern Pacific #7346.
The Couplers were Truck mounted
Any Help?
Thanks
