39 months is a long time to be without an operational layout. However, that is exactly the situation I found myself in when the Lehigh Valley Hirailers decided to end their displays in 2019. I used a lot of the modules for my home layout since they were modules I built. No more displays meant the modules were now surplus. This gave me the opportunity to build something that would be a better fit in the room I have available. So the modules left and a new layout was designed. After a lot of hard work, some missteps and other tribulations, and helpful ideas from this Forum, I am now able to say I can once again run trains! Full disclosure: I installed a temporary bridge and spiked the non-manual switches. And the yard is not installed. All this means I have a LOT of work ahead of me! But I least I can run some trains.
