Narrative:
I took a handoff on large transport X from the lga sector, large transport X was eastbound level at 5000 and had departed lga and was going to jfk. The lga controller switched large transport X over to me about 4 mi from my airspace. As large transport X came on my frequency on initial call, the conflict alert was going off between large transport X and a medium large transport Y jet. The medium large transport Y jet was nebound climbing out of 4600 and was about 2 mi away from large transport X who was still eastbound level at 5000. The first thing out of my mouth was I told large transport X the traffic (as I was giving the traffic the medium large transport Y next showed 4800 and appeared to be climbing higher than 5000), and was in the process of telling large transport X to descend, since it appeared that lga was pushing the medium large transport X jet up to top large transport X, but the lga controller called me and told me that the medium large transport Y jet is descending back to 4000, so I just told large transport X to maintain 5000. I found out later that training was in progress at the lga position, and probably the lga controller who was doing the training, was not paying attention to his trainee.

Title: LATE HDOF AND TRAINEE CTLR CLBED ACR MLG TO SAME ALT AS ACR LGT CAUSING LTSS.
Narrative: I TOOK A HDOF ON LGT X FROM THE LGA SECTOR, LGT X WAS EBOUND LEVEL AT 5000 AND HAD DEPARTED LGA AND WAS GOING TO JFK. THE LGA CTLR SWITCHED LGT X OVER TO ME ABOUT 4 MI FROM MY AIRSPACE. AS LGT X CAME ON MY FREQ ON INITIAL CALL, THE CONFLICT ALERT WAS GOING OFF BTWN LGT X AND A MLG Y JET. THE MLG Y JET WAS NEBOUND CLBING OUT OF 4600 AND WAS ABOUT 2 MI AWAY FROM LGT X WHO WAS STILL EBOUND LEVEL AT 5000. THE FIRST THING OUT OF MY MOUTH WAS I TOLD LGT X THE TFC (AS I WAS GIVING THE TFC THE MLG Y NEXT SHOWED 4800 AND APPEARED TO BE CLBING HIGHER THAN 5000), AND WAS IN THE PROCESS OF TELLING LGT X TO DSND, SINCE IT APPEARED THAT LGA WAS PUSHING THE MLG X JET UP TO TOP LGT X, BUT THE LGA CTLR CALLED ME AND TOLD ME THAT THE MLG Y JET IS DSNDING BACK TO 4000, SO I JUST TOLD LGT X TO MAINTAIN 5000. I FOUND OUT LATER THAT TRAINING WAS IN PROGRESS AT THE LGA POS, AND PROBABLY THE LGA CTLR WHO WAS DOING THE TRAINING, WAS NOT PAYING ATTN TO HIS TRAINEE.
