Skins

Skins are a feature introduced into Township within the Gold Pass event (aka Professor's Experiments) and Season Adventure events.
Skins are special decorations, which changes the looks of the Helipad & Helicopter (v7.0.5), the Train Station & (3) Trains (v7.3.0), the Airport & Airplane (v7.4.0), the Balloon (v8.1.0), the Port & (4) Ships (v8.2.0) and the Island (v8.2.0). They do not change the functionality ie speed.
You can change skins by tapping the top-left icon in helicopter pad, train station, airport, ship port and island for the respective items.
You will keep the skins after the event is over, if you have obtained them during the event.
Some skins are available in two stages during the event. Once you have received the second stage, this will be the only skin you will have available to you after the event. You have to receive the first stage before receiving the second stage. However, the this doesn't affect the island skin, which even after players have received the last stage, the previous stages were still available.
You can no longer get the skin when the according event has ended.
