I have a basic 3 loop layout. Depending on the trains I run, often I find when running multiple trains they will all go a bit slower. One specific example is when running a Dapol 68, when I then run 2 Dapol 121s (in multiple) the 68 suddenly slows down a bit. It does this with other combinations of locomotives too (mainly when running 3 trains at once, and one of them is in multiple) however no other specific examples spring immediately to mind.
I have 3 loops on my layout (the outer one leading to an under storage system) so think it would be easy to separate it into 3 power regions (inner loop & above sidings, middle loop, outer loop and underground sidings).
My layout is a very basic loop, no attempt really to make it look very realistic, with very sharp visible 90 degree bends, Each side is probably about 3m in length. The manuals for the power boosters say that size can be why they are needed so thought I better mention it.
My controller is a Hornby Elite with 2 Select walkabouts (I do not wish to change this, I am only interested in console based systems, and don't have £500 for an ECoS system). Seeing as Hornby has discontinued their power booster I am getting a tad panicky and thinking I need to buy one quickly before they all sell out so just want to make sure they are needed first. Am really annoyed I didn't buy the boosters in the hattons sales the other year now... Knew i'd probably regret that.
Thanks in advance for any answers!
