Hi and welcome on board.....

Reason for reequest for pics is to see what sort of tracks you have - even though it is all scalextric brand. Older and newer tracks have different joining connectors and thus may be an issue fitting in the older chicane with the new type of scalex track. In trerms of voltage, there should be no issue by adding some track. Issue occurs when you had a LOT of track - you get voltage drop in the area furthest from the transformer.

It is always better to add extra electrical items  to a seperate transformer, so that amperage is not affected. When you have too much on a single transformer, one can see a decline in the performance of the cars to the point that when 2 cars are running, when one accelerates, it can cause the other to de-cellerate. The older type transformers where you wrap the wires around the external electrical points are fine to use.
