‘Although the legal operator is changing, your experience won’t. You’ll continue to see the same branding, same services, and the same teams running your trains.’
I would note that it's entirely possible to "see the same branding' but still be in the process of branding changing, likewise "see the same services" whilst seeing extra services, it's even possible to "see the same teams running your trains" whilst they have a very different company ethos and management structure.
