Bachmann Spectrum HO scale GE Dash 8-40C diesel locomotive

Thanks for your comments, Ryan, very helpful indeed.

Bachmans are basic models. A good model for a begginer but for my taste they are very noisy.

To all those out there! I have been given (I think) a ho scale, Dash 8-40 CW with DCC fitted. My problem is I need to purchase some small parts etc. But unable to confirm the model. I have had a good look on lots of Webb sights. The model is a Union Pacific yellow and grey, 3 drivers on each end the unit # 6655. There are not any brand names, and the only # is on a clip on the motor (49428) it looks like a Bachmann, Spectrum. But when I copy a spare parts sheet the chassis is not quite right. My chassis is flat but the Bachmann has 2 high platforms near the 2 flywheels.
I need to purchase parts and can anybody help me identify the model please. Regards, Bob Hey. Tasmania.
