Sound Fitted NRM/Bachmann Deltic

The Bachmann / NRM Deltic model fitted with Accurascale sound and a Zimo double dumbo speaker. I need to adjust the settings on the decoder to suit the different mechanism from what Accurascale intended.
The train has two Bachmann FNA-C nuclear flask wagons followed by two Accurascale FNA-D wagons. This is not a prototypical train for 'Deltic'! It happened to be conveniently on the tracks when I was testing the installation.
