Went down to Atlantic City for the afternoon to enjoy the weather we had today. I took the train from Absecon into Atlantic City on train 4611 (11:09 a.m. arrival), and it was rather crowded. As we were pulling into the terminal, new NJT F40s 270 & 311 were there, along with the DMU car, and ALP46 4612. As we exited our train, there was a NJT police officer on the platform. I asked the officer, who followed the last group of people to the lobby, about the first two platforms, where the equipment to be on display was stored, and he said that those platforms were closed due to the conference starting at 3:30 p.m. I think my son, who is five, took a quick photo with his little camera of the 4612 as my wife and I were talking to the police officer. I did get a few photos from our train. After spending several hours on the beach and boardwalk we headed back to catch train 4618, with a 3:38 pm. departure. We got there just after 3:00 p.m. and a large portion of the waiting area was closed off for the APTA welcome party, which caused some confusion on the passengers awaiting for train 4618. There were about six NJT police officers there, which is the most I have ever seen at the Altantic City station. They stood outside of the doors of Platforms 1 & 2, which is where the equipment was and were the passengers were to exit to get to platform four for our train. I was able to take a few more photos from our train as it departed the station. As we were leaving, I did see a Septa MU car, the NJT coaches, the DMU and the two F40s. I did not see the GP9 or one of the riverline cars, but they obviously could have been out of my site.
