Bachmann OO Class 150 DMU (21pin version)

Kit: MX644D (or MS440D); RE BoomBox 40X20X10 2W speaker; LifeLink+17000uF SuperCap for stay-alive

Bachmann's 21pin Class 150 DMU is well thought out, and quite a simple one to get good sound into...

Space under the floor is provided for a flat 40x20 speaker, which is quite simple, but we went for a much better option - the Rail Exclusives Boom Box 40x20x10 instead, which sits in the same space with very little extra work.

Also added here is a 17000uF SuperCap for stay-alive. This goes via a LifeLink (not shown) which is needed with the MX644 decoder. The later MS440 does not need the LifeLink and the SuperCap can go direct to its' stay-alive connections.
