Last week I bought a Bachmann Spectrum N 4-8-2 Light Mountain Loco Item #81660. I noticed that this train is not as fast as my other Bachmann ( 4-4-0 Wildwest era B&O R.R ). I run both trains on the same track "NOT AT THE SAME TIME" and same controller. The tack and controller ( not DCC ) I bought as a set few months ago. Does this engine just run this slow or am I under powered or is there something wrong with the train.  FYI this is a great looking train.
Thanks,
Curtis
