Just arrived from Bachmann is the superb new N gauge Class 55 Deltic from Graham Farish. Supplied for review is 371-286 BR green Class 55 Deltic D9002 'KOYLI' in mid-1960s BR green condition - look out for a full review in the June issue of BRM, on sale May 8th.

Even a quick look will reveal that it's a big step forward from the model it replaces. RRP is £99.95, which when compared to some other recent N gauge diesels looks like excellent value.

Also promised are D9007 Pinza in two-tone green without yellow ends and BR blue 55005 The Prince of Wales Own Regiment of Yorkshire.

Detachable couplings are mounted in NEM pockets discreetly moulded into the front bogie framing. For those wishing to cut off the NEM pocket and fit the optional bufferbeam details, a spare bogie frame is supplied. Extra details include plastic vacuum, air and steam heating pipes and dummy couplings.

The Class 55 chassis is similar to the much-praised prototype Deltic. The low-profile chassis block houses a centrally-mounted five-pole motor and drives shafts/gears to all six axles. A six-pin DCC decoder socket is fitted, along with illuminated headcode panels and red tail lights.
