Based on a similar concept to the stretched oval, this plan uses a double crossover to make room for a large terminus station in the top right corner. Whilst the crossover increases the operating interest (especially if high speed Scalextric-style crashes are your thing) this could be avoided by constructing the layout on two levels. The station would form part of the upper layer, with tracks running down to the lower level in the top right corner and at the front of the lower left turn. Freight facilities or additional stations can be added according to taste!
