I think these do fit in the funnel, they just seem big in the pictures.
awesome setup george !!!! ante kai sta dika sou how did you thought to collect trains too?
Yes, the Seuthe smoke generators (No. 5 & 7) fit in the funnel, no problem.The smoke generators with ventilator and with larger tanks you have to place under the funnel, perhaps with a short hose to the funnel.
And is the No. 5 difficult to connect to the train battery?
