November 2020 - Latest Hot Topic - Full article in 'Model Engineer' Iss 4651 on - Petrol Electric Locomotives powered by a small engine driving an alternator generator rarely behave well. Problems with these systems was the subject of in-depth research leading to the design of some new electronics, a "Smart Regulator" which matches engine to alternator torque characteristics, solving all the usual problems along the way. See 'Smart Regulator' page.
