What's the difference between coupler and railway?
Coupler
Definition:
(n.) One who couples; that which couples, as a link, ring, or shackle, to connect cars.
Example Sentences:

(12) Therefore it is desirable that any departure from coupler response be known.
(13) Most of the aids showed a distinct correlation between coupler-related overall gain, and mould compliance.
(14) Acoustic reflex thresholds were clearly present in all testable infants at coupler sound pressure levels similar to adult data, suggesting that the relations between reflex thresholds and hearing sensitivity demonstrated in adult subjects are similarly applicable to infant subjects.
(15) When the temperature of the bone vibrators was 17 and 29 degrees C and the mechanical couplers were maintained at a constant temperature, there were little or no differences in the output of the mechanical couplers.
(16) Changes in the strength-duration curve could be accounted for by an increase in the time constant for build-up of a hypothetical coupler in the e.-c. coupling process.
(17) The relationship between these measures in the real ear canal and the changes observed in 2-cm3 and Zwislocki couplers under similar circumstances or earmold modification was also measured.
(18) We measured TRAcP-activity fluorometrically after extraction of the product naphthol-AS-BI, using the same staining solution as in cytochemical method, but without the coupler.
(19) Five frequency responses were used, two of them were defined by their response in a 2-cm3 coupler: 1) uniform coupler gain (UCG), and 2) 6 dB per rise (6 dB).
(20) The effect of hyperosmolarity was shown only in cells stimulated by lipolytic hormones, and the effects were still evident in the presence of high concentrations of theophylline, indicating the effect of hyperosmolarity is to facilitate hormone action on the receptor-coupler system of the adipocyte membrane.
Railway
Definition:
(n.) A road or way consisting of one or more parallel series of iron or steel rails, patterned and adjusted to be tracks for the wheels of vehicles, and suitably supported on a bed or substructure.
(n.) The road, track, etc., with all the lands, buildings, rolling stock, franchises, etc., pertaining to them and constituting one property; as, a certain railroad has been put into the hands of a receiver.
Example Sentences:
(1) The Trans-Siberian railway , the greatest train journey in the world, is where our love story began.
(2) "Speed is not the main reason for building the new railway.
(3) It is the biggest privatisation since John Major sold the railways in the 1990s.
(4) Sometimes it can seem as if the history of the City is the history of its crises and disasters, from the banking crisis of 1825 (which saw undercapitalised banks collapse – perhaps the closest historic parallel to the contemporary credit crunch), through the Spanish panic of 1835, the railway bust of 1837, the crash of Overend Gurney, the Kaffir boom, the Westralian boom, the Marconi scandal, and so on and on – a theme with endless variations.
(5) The Conservatives have held back the development of garden cities on the scale necessary, but if Liberal Democrats are part of the next government, we will ensure at least 10 get under way – with up to five along this new garden cities railway, bringing new homes and jobs to the brainbelt of south-east England.” The Lib Dems insist they are planning to act in the national interest and are not motivated by electoral considerations.
(6) Demolition of a steel railway bridge was carried out by nine workers using flame-torch cutting.
(7) She consciously destroyed the workforces in places like the railways, for example, and the mines, and the steelworks … so that transition from adolescence to adulthood was destroyed, consciously, and knowingly.
(8) The railway between Norwich and Ely was blocked when strong winds caused power lines to fall across the tracks.
(9) Where the cycle track is signed to the left, continue on the footpath straight ahead, which runs beside the main railway - this will take you to Didcot station.
(10) A Department for Transport spokesman said the money was available now, adding that it was to deliver 10 projects along the western route, including works at Cowley Bridge in Exeter, which would improve the railway's ability to withstand extreme weather.
