I would put in a plug for getting a 25 to 30W soldering iron, multicore electrical solder and some wire, instead of the Hornby power connection clip. A good hobby store will show you the 'how to' of soldering as part of the sale if you don't have experience. This is beneficial both for adding plenty of powerfeeds around a layout, and to enable DCC decoder fitting to any loco: also useful for a host of model railway and other repair tasks. After a while you will wonder how you got by without this facility.
