ALCO T-6

The Alco T6 (DL 440) was a diesel-electric locomotive of the switcher type rated at 1,000 horsepower (750 kW), that rode on two-axle trucks, having a B-B wheel arrangement.

The 'T' stood for 'Transfer', meaning this locomotive was capable of faster transition and higher sustained speeds than the regular 'S' - type yard switcher series.

Original Owners

Survivors

The Delaware Coast Line Railway, the Ohio Central Railway and the Arkansas & Missouri operate the T-6. Ohio Central's T-6 is unique because it was the only one built with Hi-Ad trucks. 14 T-6's survive in all.

Pennsylvania RR 8427 survives as Georges Creek Railway 101. It was that railroad's first locomotive acquisition and is often used to switch the NewPage paper mill at Luke, Maryland.

Newburg and South Shore Railroad 1017 at Cargill at there Dana, Indiana elevator. As of 1-16-2016, the stack bagged, and restensiled GLLX 1017. Newburg and South Shore Railroad 1016 survives as Middletown and Hummelstown Railroad 1016.

Fax

Fax (short for facsimile), sometimes called telecopying or telefax, is the telephonic transmission of scanned printed material (both text and images), normally to a telephone number connected to a printer or other output device. The original document is scanned with a fax machine (or a telecopier), which processes the contents (text or images) as a single fixed graphic image, converting it into a bitmap, and then transmitting it through the telephone system in the form of audio-frequency tones. The receiving fax machine interprets the tones and reconstructs the image, printing a paper copy. Early systems used direct conversions of image darkness to audio tone in a continuous or analog manner. Since the 1980s, most machines modulate the transmitted audio frequencies using a digital representation of the page which is compressed to quickly transmit areas which are all-white or all-black.

History

Wire transmission

Scottish inventor Alexander Bain worked on chemical mechanical fax type devices and in 1846 was able to reproduce graphic signs in laboratory experiments. He received patent 9745 on May 27, 1843 for his "Electric Printing Telegraph."Frederick Bakewell made several improvements on Bain's design and demonstrated a telefax machine. The Pantelegraph was invented by the Italian physicist Giovanni Caselli. He introduced the first commercial telefax service between Paris and Lyon in 1865, some 11 years before the invention of the telephone.
