Stud contact electrification on model railways : ウィキペディア英語版 | Stud contact electrification on model railways
Stud contact is a system of electrification for model railways. It was popular before the widespread use of plastics since it permits the use of metal sleepers (ties) or track bases, and does not require an insulated section in each wheelset. ==Overview== The system is a modification of the third rail electrification system designed for use on systems where an actual third rail would be unprototypical. Studs are laid at regular intervals, generally down the centre of the track. They are connected electrically and insulated from the running track. A flat ski under the locomotive that is always contact with at least one stud acts as the collector. Because the collector acts on a small area, the stud, the collector cleans the stud. This ensures the system has good electrical contact. This means the system works well even on track covered in oil, sand and the general detritus of a garden railway.
