The best way to run this is on DCC as you get far more sounds available. There is a reprinted instruction manual which gives all the necessary info about the decoder and its functions etc. Personally I feel a better speaker would enhance the sound as the supplied Hornby speaker is not a particularly good quality speaker. That said it is a perfectly useable model. Lights are directional and all work.
Some loose detail parts are supplied in a resealable bag these include the missing roof horn, ploughs and tension lock couplings plus several cables and odd loose detail parts. Only what you can see is included if it's not on the Locomotive or in the photos it's obviously not there. These Locomotives are prone to having missing cab end lamp brackets and this one is no exception.
