Hello My son is into Hornby and has been gifted a few sets. I have created a 2 loop with shunting track and now want to make sure everything stays well connected. (Problem I had with mine when I was young...) I haven’t really got the time right now to place a dropper on every piece of track; however, are there any time efficient ways of keeping things decent over the longer term or do I just need to bite the bullet and do it? I am running DC and just he just received a new hm6000 controller. thanks
