Looks like #BlueBrixx is axing their series of 6W #train sets in favour of 8W: almost all 6W #locos and #coaces have been designated "EOL" (end-of-life) while quite a bunch of new 8W #models have been announced.
Doesn't mean threy are gone tomorrow but if you like their 6W rolling stock you should keep an eye on availability.
Customers seem to prefer 8W models and in terms of detail I can't blame them.
