  Double track - Wikipedia, the free encyclopedia
In the earliest days of railways in the United Kingdom, most lines were built as double track because of the difficulty of co-ordinating operations prior to the invention of the telegraph.
The double track lines in any country generally keep to one side of the road, which is not necessarily the same side that road vehicles in that country keep to.
A double track tunnel with restricted clearances is sometimes singled to form a single track tunnel with generous clearances, such as the Connaught Tunnel in Canada or the Tickhole Tunnel in New South Wales.

 Single/Double Track
If single track construction is used, then there need to be periodic passing sidings where a car traveling in one direction can wait while one going in the opposite direction passes (see photos).
Single track construction is considerably cheaper to build but has lower capacity as the number of cars operating in each direction is limited by the spacing of passing sidings.
Double track construction costs are higher than for single track, but the capacity is much higher as streetcars traveling in opposite directions may pass at any point.

 Tram - Wikipedia, the free encyclopedia
Cable cars are pulled along a rail track by a continuously moving cable running at a constant speed on which individual cars stop and start by releasing and gripping this cable as required.
More recently, a modern equivalent to the old stud systems has been developed which allows for the safe installation of a third rail on city streets, which is known as surface current collection or ground-level power supply; the main example of this is the new tramway in Bordeaux.
In narrow situations double-track tram lines sometimes reduce to single track, or, to avoid switches, have the tracks interlaced, e.g.

 GCR Double Track
The initial scheme, whilst impressive, would have resulted in an isolated section of double track and was extended to include relaying the second line between Rothley and Quorn to give a worthwhile length of double track main line.
Track was initially laid on the previous down line formation from the north end of Rothley and through Swithland, loops being added on both down and up sides of the line at Swithland.
The double track between Loughborough and Rothley was commissioned on 1st June 2000, although some funding is outstanding.

 Enroute
For example track error is 6° north [left] and original heading 079° magnetic, thus the heading to regain track is 079 plus 12 = 091° magnetic [096° compass] and we fly that for 24 minutes – the same time as that flown on the original heading.
For example the track error was 6° and the heading to regain track is 091° magnetic, thus the heading to maintain track is 091 minus 6 = 085° magnetic [090° compass] and we fly that until either a new position fix is obtained or we reach the waypoint.
Whenever a position fix is obtained, whether it is on-track or off-track, it is advisable to calculate the ground speed achieved and to re-estimate the ETI for the leg, ETA at the next waypoint and the destination.

 Trains.com - Single-track or double-track?????   (Site not responding. Last check: 2007-11-06)
Generally speaking, double track is better for small layouts because it allows you to keep your trains running.
Single track works well for larger layouts because there is a better ratio of running time to waiting time and you have multiple locations for meets and passes.
I like a double track because I run my RR by myself and like to have activity on the mains while I switch at local industries or yards etc. My layout is a 14 X 9ish around the wall.

 F1G - Online Information article about F1G
provision of sidings, connected with the running tracks by points, for holding spare rolling stock and to enable carriages to be added to or taken off trains and engines to be changed with as little delay as possible.
separate tracks are sometimes appropriated to the use of light engines and empty trains, on which, they may be run between the platforms and the locomotive and L.., carriage depots.
One of these, employed in America, is known as " poling." Alongside the tracks on which stand the trains that are to be broken up and from which the sidings diverge subsidiary tracks are provided for the use of the shunting engines.

Connect a feeder from the two wire track bus for that main track to its corresponding rail for each section of track that has been joined to the previous rail by a metal rail joiner.
The CONTROLLER is keeping track of the train and when crossing from one main to the other, it will switch to the corresponding BOOSTER to continue to run the train.
If your layout is point to point double track or a double track oval type of configuration then wire all the inside rails to one bus wire and all the outside rails to another bus wire.

 Home Recording dot com BBS - Double Track Vocals?
Can someone explain what double tracking is. I just did a search for it and came up with nothing to do with whats being talked about here.
The easiest way to double track a vocal is if you have a computer sequencing program.....You can just clone or copy the track to another track without singing it over again....Later on you can then bounce them back to one track and they will retain their separate settings e.g.
Obviously the benefit of double tracking (or multi tracking) lead vocals, is a fatter sound, but, there are downsides as well - you lose some of the nuances and a little intimacy in my opinion.

 Double-track onto train turntables   (Site not responding. Last check: 2007-11-06)
In order to ensure that all rail ends are radial (here at 7 degrees separation) approaching double tracks (from the right) must separate before curving back onto the table.
Here approaching tracks are at conventional 80mm running-line centres, but widened to 100mm centres on the table for easier handling of stock.
If space constraints require the turntable to be directly attached to the visible layout, this can be done by using gauntletted tracks on the table.

 History
In 1917 the NC and St L Railway and the Chicago, Burlington, and Quincy Railway jointly constructed a rail line and a double track bridge between Paducah and Metropolis.
The bridge (which is listed by the Encyclopedia Britannica as the world’s longest simple truss bridge) made a gateway connection between the NC and St L in the south and the CB and Q or Burlington Route for the north and west.
By 1974 the L and N reduced its employee force in Paducah and moved the freight office to the yards at 6th and Norton.
