In response to AFNYer, the 1 route sadly cannot have more trips going to Jersey City. That is for several reasons. The first one is because on a average weekday, a majority of the Hilton buses are used because they have so many routes from that garage. If that were to happy, then 1 would have to split with 2 garages. The only garage it would be able to split with is Greenville. However, Greenville exhasts almost all of their buses because they have less routes. You see, Greenville only has 6 routes. But, they use so many of their buses on weekdays. If you take a look at MyBusNow off the rush hour, you see about 10 80s, 7 87s and MANY 126 trips. To respond to your Neoplan comment, I would like to have that, but they Neoplans will not be able to handle Ivy Hill Loop. They cannot end there. If there were to be Neoplans on the 1, they would have to add a special trip from Newark to Jersey City and back.
My favorite routes:
#37: Runs from Ivy Hill Loop to Newark Airport (All Terminals and North Area): It is a very simple route and is normally not overcrowded. On an average weekday, the people using it are airport workers that live in the Ivy towers. The bus runs about 2 per hour from 5 to 8 AM then resumes to once per hour, then trips start at Irvington Terminal at noon. The trip is 45 minutes. I normally use it to Terminal C so I can connect to the 62 to get to IKEA.
#108: Newark to New York (via Union City): Once again, a very simple route. The bus starts near the Colonnade Park Apartments. The bus then passes through Broad Street Station then passes through Newark Penn. It is one of the two suburban routes from Hilton, 107 is the other one. Drivers normally alternate from these two routes at PABT. 108 on weekdays has some trips that do NOT go through Union City in the early morning hours. They operate once per hour, and the normal ridership only has a few people standing.
