Playing it cool

Regen braking has a place here, too, if you can shove the heat from the necessary resistors outside. If it's regen braking, rather than rheostatic, the heat goes as energy to other trains and not into resistors. Ish. On AC, absolutely right; on DC, you need banks of resistors as well because putting it back to the grid if there isn't a conveniently placed train to take it is Too Bloody Hard. However, given the traffic density on LUL, most of the time there'll be someone accelerating while you're breaking so it should work out OK... -- John Band john at johnband dot org www.johnband.org |
