electrify the remainder of the Port Jefferson Branch between the Huntington and Port Jefferson stations, in addition to the remainder of the Oyster Bay Branch between the East Williston and Oyster Bay stations to enhance service in the served areas and to upgrade service capacities along the lines; electrifying these lines could lead to more frequent direct service to and from Manhattan, as diesel trains are not allowed in Penn Station and dual-mode trains exceed the clearance for the future East Side Access tunnels. Law enforcement The Long Island Rail Road Police Department, founded in 1868, was absorbed along with the Metro-North Railroad Police Department to form the Metropolitan Transportation Authority Police Department (MTA Police) in 1998. Criticism and controversy Passenger issues The LIRR has a long history of tense relations with its passengers. Daily commuters have long had complaints about the LIRR's service. According to a 1999 article in The New York Times, the LIRR's service woes were long considered part of the "unholy trinity of life on Long Island," along with the Long Island Lighting Company's high rates and the Long Island Expressway's traffic snarls. Various commuter advocacy groups have been formed to try to represent those interests, in addition to the state mandated LIRR Commuters Council. The LIRR has been criticized for not providing additional service to the East End of Long Island as the twin forks continue to grow in popularity as a year-round tourist and residential destination. Demand is evidenced by flourishing for-profit bus services such as the Hampton Jitney and the Hampton Luxury Liner and the early formative stages of a new East End Transportation Authority. Local politicians have joined the public outcry for the LIRR to either improve the frequency of east end services, or turn the operation over to a local transportation authority. Critics claim that the on-time performance (OTP) calculated by the LIRR is manipulated to be artificially high. Because the LIRR does not release any raw timing data nor does it have independent (non-MTA) audits it is impossible to verify this claim, or the accuracy of the current On Time Performance measurement. The percentage measure is used by many other US passenger railroads but the criticism over accuracy is specific to the LIRR. As defined by the LIRR, a train is "on time" if it arrives at a station within 5 minutes and 59 seconds of the scheduled time. The
