I know you asked Kevin, but the numbers just refer to siding capacity. 5-3-3 means a capacity for 5 cars, 3 cars and 3 cars. Most people use a mainline anyway for the first 'siding' so the second and third numbers are the ones for concern. A 2 car siding fits a lot better within the loop given (and 2 of them at that!) than a 3 car siding.... Unless you cheat and use the K-line ore cars that went with the Porter locomotive
