Being a complete "novice" I would appreciate your help on the following.
Ideally, I wanted to go down the DCC route, but perhaps I need to "walk before I gallop" so I recently visited a well known dealer in the Bedfordshire area of UK, and explained that I need a basic control system i.e. a Transformer and a Controller.
I was advised to purchase an LGB Transformer Model 50110, ( I will be running an "Aristocraft Mallet G scale loco & rolling stock ), and a Controller ( again, a Lehmann product, ) made in the form of a building, with the control dial inside it ( this item has no product or model number on it, so I can not identify it further ).
Subsequently, on a visit to a meeting of the local "G" scale modelling society, I was informed by one of their members ( after showing him the two items I had purchased ), that (a) the Controller unit was only powerful enough to move the loco, and certainly would not power a loco plus rolling stock, and (b) the Transformer was an AC unit, that could only be used for accessories ( signals, points, lights etc ) - not for powering a loco, and that I should have purchased a DC Transformer.
Before I return to the supplier who sold me these two items - is this "expert" correct ?
Any help would be greatly appreciated from you "life-timers" out there.
