Model Rail (Heljan) British Rail Class 11 shunter

 

Today on Pix Valley we are proud to announce our latest arrival, in pristine condition after extensive rebuild to full running order 12100 British Rail Class 11 shunter (the daddy of the 08 gronk) as normal procedure in Pix Valley it was run on the rolling road for 30 minutes in each direction before being chipped. Unfortunately I noticed that when running in the cab light didn’t work! Waved the magic wand till I was blue in the face LOL I selected a Zimo MS581N18 sound chip from https://www.youchoos.co.uk/ using the Class 08 sound file as both locomotive share the same English Electric 6KT engine. Installation is very straight forward two screws behind the side tool boxes release the body taking care to tease it up as its very tight fit. The cab light issue was down to one of the bronze tabs detached from the keeper plate screwed to the under side of the roof moulding. A spot of cyanoacrylate solve the issue.  Fit the MS581 after the blanking plug was removed there is a built in speaker on the PCB all that remains was to replace the body shell that’s it job done. Due to the orientation of the chip to clear the cab light pad it was necessary to set the decoder to reverse polarity, CV’s were tweaked to

CV 2 Start Voltage 5
CV 3 Acc Momentum 20
CV 4 Dec Momentum 15
CV 5 Top Voltage 0
CV 6 Mid Voltage 0      
CV29 reverse direction 39
CV266 Volume 75
