Do you know the problem that digital locomotives sometimes falter on points and bumps? This can be solved with a buffer capacitor circuit. This is not new, it has been around for a long time and many articles have been written about it. SMD can also be found on the internet.
SMD is a perfect technique applicable in all scales and due to the small size of SMD it is possible to build in a good capacity of buffer in a locomotive. A capacitor charges itself with voltage and when it drops out it discharges itself so that the dip is absorbed.
For the LocBuffer an extensive manual is available on our website www.domburgtrainsupport.com
