no, unless that is new related did not talk about saving the spur. in fact although they were officially non-committal they made it clear it was in the way and they wanted to tear it down (in fact its not pictured at all on those renders). so as far as the spur goes i hope they have changed their minds, but this is exactly why the city must step in to protect the rest of the high line.
edit: re-reading your post i think you may have misinterpreted. the "spur" is just the part of the se corner that goes across 30th st and hangs over 10th avenue (another great future cut-out viewing platform!).
however, i will add they did verbally commit to keeping the rest of the railyard high line. that is, the major section that turns west, runs up 12th ave and wraps around the railyards to w34th st. that is what you see in renderings.
however, while i applaud related for facing the public, i wouldn't trust one bit of this verbal discussion to any developer. activism is still vitally important to protect the whole railyard section. here's news about the next cb4 forum:
