A radical idea

Rather than another branch line terminus, instead, a passing halt on a branchline. This idea takes advantage of the availabilty of Pola's old kit of Rothhausen, an example of the Agenturgebäude prefabricated wooden station. 

The simple trackplan needed some thought to shunt, The way it would work, is the loco with the wagon(s) to be deposited, would detach from the train proceed past the turnout, set back into the siding, collect the wagon(s) already there, pull forward and deposit those wagons onto the train and then put the arriving wagon(s) into the siding and then continue on its way.

A few images of Rotthausen

 

The station above, Rothhausen, is feasible on three boards using these clever laser cut modules that are available in a variety of sizes from Grainge & Hodder which can be combined with laser-cut cassettes from Intentio Models
