Boktips....och en del frågor...Kondenslok (Arkiv/forskning/litteratur)

Kondenslok har funnits. Tyskarna byggde sådana under kriget (BR 52 med kondenstender) för vattenfattiga områden. Sydafika hade också sådana byggda efter motsvarande koncept(?). Draget ordnades med en ångturbindriven fläkt.
Jag har för mig att de fungerade rätt bra, men krävde mer underhåll än konventionella lok. Jag har sett en vidofilm från Sydafrika där ett kondenslok används. Jag tror det var ett museilok. Det var bara fläktturbinen som hördes när loket drog i gång. En märklig ljudupplevelse.
