No problem, David - there is one thing I should have added, which is that the Massoth system (unlike MTS2) has the ability to select different settings for each loco, the most important one being the speed steps, but you can also set whether it is a Parallel or Serial decoder if you are running some older locos. MTS2 was only capable of running with 14 speed steps, but the Massoth kit can handle 14 or 28 (or 128, but you don't need to worry about that...). For LGB factory-chipped locos you will need to select 14 speed steps, otherwise you have strange effects like the lights flashing on and off. Now, once you have your Massoth kit (if you choose to go for it) you will find that you can pre-enter the settings of each loco you have into the Navigator handset, and then store that data - so every time you call up a particular one of your locos all the config will be stored ready for you; alternatively, selecting the right settings on the fly for each loco when you start a running session is very quick and simple, just a couple of button-presses, and that will store a "temporary" file that will stay active until you switch the system off at the end of that running session. Don't let any of that put you off, it's very easy to do - you just key in the loco number, choose 14 or 28 speed steps, choose P or S mode, and off you go!
