The ABB ALP-44 is an electric locomotive which was built by Asea Brown Boveri (Sweden) between 1989 and 1997 for the New Jersey Transit and SEPTA railway lines. As of 2014, only SEPTA still operates the ALP-44 in revenue service, as New Jersey Transit has retired its fleet.
The ALP-44 was originally ordered for New Jersey Transit's electric lines, with fifteen units, designated ALP-44O ("O" denotes Original) and numbered 4400 through 4414, delivered in 1990, with prototypes 4400 and 4401 in late 1989. An option order for five more units, designated ALP-44E ("E" denotes Extended) and numbered 4415 through 4419, were delivered in 1995. The final order for 12 ALP-44M units ("M" denotes Microprocessor) numbered 4420 through 4431 were delivered in 1996 and into early 1997 for the new Midtown Direct service.
As of late 2011, all NJ Transit ALP-44 O, E, and M locomotives have been retired. All units were retired with the delivery of the remaining ALP-46A locomotives, except 4405, 4407, and 4409, which were assigned to ACES; however, these remaining units were also placed into retirement with the cancellation of ACES service in early 2012. Units 4402, 4403, 4408, and 4410 were leased by Amtrak for work train service through the Hudson River tunnels for a period of time during summer 2011, but have since been returned.

Alpı is a Turkic word that may refer to:
Aleph is the first letter of the Semitic abjads, including Phoenician 'Ālep , Hebrew 'Ālef א, Aramaic Ālap
, Syriac ʾĀlap̄ ܐ, and Arabic Alif ا.
The Phoenician letter is derived from an Egyptian hieroglyph depicting an ox's head and gave rise to the Greek Alpha (Α), being re-interpreted to express not the glottal consonant but the accompanying vowel, and hence the Latin A and Cyrillic А.
In phonetics, aleph /ˈɑːlɛf/ originally represented the glottal stop ([ʔ]), often transliterated as U+02BE ʾ , based on the Greek spiritus lenis ʼ, for example, in the transliteration of the letter name itself, ʾāleph. Even in early use, it occasionally functioned to indicate an initial unstressed vowel before certain consonant clusters, the prosthetic (or prothetic) aleph. In later Semitic languages it could sometimes function as a mater lectionis indicating the presence of a vowel elsewhere (usually long). The period at which use as a mater lectionis began is the subject of some controversy, though it had become well established by the late stage of Old Aramaic (ca. 200 BCE).
