Hc 527 i Mjölby - 1970 - (Järnväg allmänt)

Troligen från F-lok. Man bytte ut de ursprungliga strömavtagarna på F-loken och satte dem på långsammare lok bl.a. även på Bk-lok.

Varför kostade man på byte av strömavtagare på H-lok? På vilket sätt var de fd F-loksströmavtagarna bättre? Eller var H-lokens strömavtagare dåliga eller gravt slitna?

Och, lite besides, varför bytte man strömavtagare på F-loken?
