The eBUS 2-wire interface is an asynchronous serial port with active-low voltage that exchanges 8-bit bytes with start and (single) stop bits (no parity bit), at a symbol rate of 2400 baud, and can be implemented with a standard UART plus a voltage converter.
A short, lightweight and fast train passing over an insulated blockjoint may disappear from the departing track circuit before it appears in the arriving track circuit, allowing false clear signals to be given. This problem can be overcome by introducing a time delay of say 1–2 seconds into the departing track circuit.
No. 4000 at the head of the Denver Zephyr train. Photo taken by Otto Perry on February 26, 1938. With the modifications increasing the locomotive's tractive effort to 47,700 pounds and top speed to over one hundred miles per hour, No. 3002 was reclassified as an S-4a, and it was renumbered to 4000.
The AC4400CW was the first GE locomotive to offer an optional self-steering truck design, intended to increase adhesion and reduce wear on the railhead. [1] This option was specified by Canadian Pacific Railway, Cartier Railway, CSX for their units 201-599, Ferromex, Ferrosur, and Kansas City Southern Railway.
Designated the 4000 class, the first was delivered in October 1999. [3] After an extensive evaluation process, the first entered service in May 2000 with all in service by May 2001. The dramatic increase in tractive effort and adhesion of the AC traction motors compared to the previous DC traction locos exceeded all expectations and ...
In any given country, rail traffic generally runs to one side of a double-track line, not always the same side as road traffic. Thus in Belgium, China, France (apart from the classic lines of the former German Alsace and Lorraine), Sweden (apart from Malmö and further south), Switzerland, Italy and Portugal for example, the railways use left-hand running, while the roads use right-hand running.
TSFC or SFC for thrust engines (e.g. turbojets, turbofans, ramjets, rockets, etc.) is the mass of fuel needed to provide the net thrust for a given period e.g. lb/(h·lbf) (pounds of fuel per hour-pound of thrust) or g/(s·kN) (grams of fuel per second-kilonewton). Mass of fuel is used, rather than volume (gallons or litres) for the fuel ...
The International DuraStar line, known as the 4000 series prior to 2008, is a line of medium-duty trucks produced by Navistar International from 2001 until 2018. [1] Introduced as the successor to the International 4000 series of 1989–2001, the 4000 series was renamed the DuraStar in 2008.
