A TD interpose refers to the act of inserting a train description into a TD berth. If a TD berth already has a description, it can be interposed by right-clicking on the berth and selecting Interpose from the menu presented. Alternatively, press I, enter the description, and then click on the nearest signal (or exit arrow) to the TD berth.
