Is this the newest version of the class 56, with a centre motor and drive to both bogies? - I reckon it must be because this is the only version with the rotating fan gimmick - if so ignore all the previous posts which are about the earlier bogie drive versions, a completely different animal.

It has been in a box for years and never run I take it? Very common to find that it simply doesn't go well at first. Current collection will be poor, due to slight surface oxidation of the wheel tyres and the wiper contact patches; also it is quite likely that the grease in the drivelines has set fairly hard in places. The motor brushes may well be none too well bedded in either.

The cure is usually very simple, give it a good run; and this is best done on a roundy roundy circuit with a DC controller at a medium speed. It may need a couple of hours before it glides along in both directions, it should coast on the flywheel momentum when power is snapped off. Then fit the decoder and retest. The fan drive is a hindrance to smooth running BTW, the little O ring that drives it is likely to have taken a set while in storage and will always impose a variable load on the drive line, snip through and remove would be my best advice...

Save your cash as regards a rolling road. Unless the loco is only going to run in a straight line, it doesn't really exercise the mechanism fully, and also it is no use for rolling stock which also benefits from a test run. The minimum alternative of a piece of 3/4" Ply 3'6" by 4'6" to take a small oval using 2nd radius track for the curves will cost a lot less and do a better job with the loco being reversed on quarter hours, and turned around on the track every half hour and hour, can be stood flat against a wall or the back of a cupboard for storage. When you start to build a permanent layout, use the ply to make structural members, little waste.
