Pilning railway station is a minor station on the South Wales Main Line near Pilning, South Gloucestershire, England. It is 10 miles (16 km) from Bristol Temple Meads and is the last station on the English side before the Severn Tunnel through to Wales. It is managed by Great Western Railway, who provide the two train services per week from the station.

The station was opened by the Bristol and South Wales Union Railway in 1863, but was resited in 1886 when the Severn Tunnel was opened. The station had an extensive goods yard, boasting one of the largest railway communities in the Bristol area, and operated a motorail service to Wales. In 1928 the original station was reopened on the Severn Beach Line, which allowed passengers and freight to reach Avonmouth Docks, though this only lasted until 1964. The goods yard was closed in 1965, and the station buildings later demolished, with very little in the way of facilities. Passenger services also declined, to two trains per day in the 1970s and the current service level of two trains per week in 2006. (Full article...)

The City of Denver was a streamlined passenger train operated by the Union Pacific Railroad between Chicago, Illinois, and Denver, Colorado. It operated between 1936 and 1971. From 1936–1955 the Chicago and North Western Railway handled the train east of Omaha, Nebraska; the Chicago, Milwaukee, St. Paul and Pacific Railroad (the "Milwaukee Road") handled it thereafter. The train was the fastest long-distance train in the United States when it debuted in 1936, covering 1,048 miles (1,687 km) in 16 hours. For almost its entire career its principal competitor was the Chicago, Burlington and Quincy Railroad's Denver Zephyr. When Amtrak assumed operation of most intercity trains in the United States in 1971, it discontinued the City of Denver, preferring to use the Burlington's route between Chicago and Denver.

On its launch in 1936 the City of Denver used a pair of articulated trainsets built by Pullman-Standard. The streamliners would remain in service until 1953, when conventional locomotive-hauled rolling stock replaced them. The City of Denver always carried both sleeping cars and coaches. A notable feature of the 1936 version of the train was the "Frontier Shack" tavern, which had the feel of a Western saloon. (Full article...)

Diver communications are the methods used by divers to communicate with each other or with surface members of the dive team. In professional diving, diver communication is usually between a single working diver and the diving supervisor at the surface control point. This is considered important both for managing the diving work, and as a safety measure for monitoring the condition of the diver. The traditional method of communication was by line signals, but this has been superseded by voice communication, and line signals are now used in emergencies when voice communications have failed. Surface supplied divers often carry a closed circuit video camera on the helmet which allows the surface team to see what the diver is doing and to be involved in inspection tasks. This can also be used to transmit hand signals to the surface if voice communications fails. Underwater slates may be used to write text messages which can be shown to other divers, and there are some dive computers which allow a limited number of pre-programmed text messages to be sent through-water to other divers or surface personnel with compatible equipment.

Communication between divers and between surface personnel and divers is imperfect at best, and non-existent at worst, as a consequence of the physical characteristics of water. This prevents divers from performing at their full potential. Voice communication is the most generally useful format underwater, as visual forms are more affected by visibility, and written communication and signing are relatively slow and restricted by diving equipment.

King's Highway 90, commonly referred to as Highway 90, was a provincially maintained highway in the Canadian province of Ontario. The route connected Barrie with the town of Angus and CFB Borden. The highway was designated in 1937. During the early 1960s, the highway was realigned within Barrie in order to have it interchange with Highway 400; originally the route followed Tiffin Street.

King's Highway 80, commonly referred to as Highway 80, was a provincially maintained highway in the Canadian province of Ontario. It travelled in an east–west direction south of Sarnia from Courtright to Strathburn. Beginning at the St. Clair Parkway near the shores of the St. Clair River, the route travelled 69.6 kilometres (43.2 mi), intersecting Highway 40, Highway 21 and Highway 79 before ending at Highway 2. In addition to the towns at either terminus, Highway 80 serviced the communities of Brigden, Glencoe and Alvinston. The entire route was and remains two lanes wide.

Highway 80 was first designated in 1937, travelling east from Highway 79 in Alvinston to Highway 2 in Strathburn. Most of the original winding highway was bypassed in 1962, and the route was extended west in 1963 to what was then Highway 40, now the St. Clair Parkway. It remained this way for over 30 years before being decommissioned as a provincial highway entirely in the mass downloading of highways in 1997. Today the route is known as County Road 80.

New York State Route 48 (NY 48) is a 28.20-mile (45.38 km) north–south state highway in Central New York in the United States. The southern terminus of the route is located at Interstate 690 (I-690) exit 3 near the interchange between I-690 and the New York State Thruway (I-90) in Van Buren, northwest of Syracuse. The northern terminus is located at an intersection with NY 104 in Oswego. In between, NY 48 passes through the riverside communities of Baldwinsville and Fulton and runs alongside both the Seneca River and Oswego River. For most of its route, NY 48 serves as an alternate route of NY 481. The routes share similar alignments along the Oswego River from the Syracuse area to Oswego, with NY 481 following the eastern riverbank between the two locations.

When the route was originally assigned as part of the 1930 renumbering of state highways in New York, it extended southward into downtown Syracuse. NY 48 was truncated to Van Buren after I-690 was built over portions of the road in the late 1950s and early 1960s. The portion of former NY 48 that was not supplanted by I-690 was turned over to Onondaga County; however, the state reacquired the segment adjacent to the New York State Fairgrounds in 1980. Around 1931, a suffixed spur of NY 48, New York State Route 48A was designated as an alternate from Oswego to the town of Minetto. The route was deleted from the state highway system around 1940.
