As Pers says, it's not in the Citadel. Also, we don't know how many years in the past it is - obviously at least about 740! I mean, even for Time Lords, that's plenty of time to change policy and defence systems! So, maybe they haven't invented the transduction barrier yet, or have much need for it - maybe TARDISes are still only on early models & the chances of an unexpected materialisation aren't high. Or maybe this TARDIS is developing skills beyond TARDISes back in the day - she's been through a lot since then & may be able to get round all sorts of things. I'd agree if it had landed smack back in the Citadel as when we see that in the 70s and 80s, but it isn't. We don't know for sure that it even is Gallifrey, just that it's somewhere the Doctor went during his childhood. Which makes Gallifrey likely - but then I kind of thought the barn in the 50th wasn't, and that's where it was, isn't it?

Besides, it just made me cry so much I can't stop, mostly in a good way, so I don't care!
