DCC Ready 2 Bil and 2 Hal

Hi All.   Even though I have been working with DCC fo a couple of years, I still have Loco’s to add a Decoder .First of all the Hornby 2 Bil and 2 Hal. Would someone please recommend suitable Decoders ? Best wishes  Kevin 

Lenz Standard+ for both.  For the 2-BIL the socket is in the inner end of the motor coach, and the decoder then sits on top of the seat partitions out of sight.  For the 2-HAL the socket is next to the motor, and the decoder fits underneath the seating unit. 

Hi Robert.  Thank you for your reply.  Strange that one would have expected both chassis to be alike. Best wishes. Kevin
