With all of the new Passenger train stations becoming available lately you might want to consider adding a train shed or two to compliment each other. They are available in several sizes and configurations including the all new 29 inch wide version coming soon. See computer rendered drawing below showing all three sizes. The new 29 inch size has a lot of the same attributes as the 48 inch size, however includes much more detail.
thanks.
