I was looking through the br leaflets for the prototype and found one that shows an 8 car set with two ndm's a tf and a ts in addition to the two tbf's and two dts. Which as an 8 car set might run on more layouts. But does not show on the apt-p website configurations, does anyone know if thismactually ran or was it just in the promo leaflets?
similarly a 6 car half set and, interestingly a 9 car full set that is marked up as having a single power car with one dts and one brake coach " no public access"
any better info would be appreciated.
