Hornby OO Class 91 Electric

Kit: MS440C

This Hornby Class 91 was supplied to us with a pair of cube-type speakers already installed, so the MS440C sound decoder just plugs straight into the 21pin DCC socket. A 'sample' 1000uF is supplied with the MS440, so a home was found for this above the drive shaft cavity.

A special version of our Class 90 sound project was used here, because the Hornby model has some specific lighting outputs that have to be configured correctly.

The physical outputs are:
F0F/F0R: directional lights
FA1: disables whites
FA2: disables reds
FA3: front cab
FA4: rear cab

FA3/FA4 must be Logic Level outputs for these to work.
