## How much horsepower does a 2 6 6 locomotive have?

The powerful 2-6-6-4s were capable of more than 5000 drawbar horsepower at 45 mph (72 km/h) and could reach 70 mph (110 km/h), and could lug heavy coal trains. They were used until dieselisation in 1959. One locomotive, Norfolk & Western 1218, was preserved and in 1987 was restored to running order, running on excursions until 1991.

## Why was the 2 6 6 4 invented?

The 2-6-6-4 was a fairly late development, a product of the superpower steam concept, introduced by the Lima Locomotive Works, which encouraged the use of large fireboxes supported by four-wheel trailing trucks. Such a firebox could sustain a rate of steam generation to meet any demands of the locomotive’s cylinders, even at high speed.

## Can a function be related to more than one value?

Value “5” is related to more than one value in Y. (But the fact that “6” in Y has no relationship does not matter) Vertical Line Test. On a graph, the idea of single valuedmeans that no vertical line ever crosses more than one value. If it crosses more than onceit is still a valid curve, but is not a function.

## Is the number 4 a function or a relationship?

(Notice how both 4 and -4 relate to 16, which is allowed.) It is a relationship, but it is not a function, for these reasons: On a graph, the idea of single valued means that no vertical line ever crosses more than one value. If it crosses more than once it is still a valid curve, but is not a function.

## Which is greater 2 / 6 or 2 / 4?

0.333 is not greater than 0.5. Therefore, 2/6 is not greater than 2/4 and the answer to the question “Is 2/6 greater than 2/4?” is no. Note: When comparing fractions such as 2/6 and 2/4, you could also convert the fractions (if necessary) so they have the same denominator and then compare which numerator is larger.

## What kind of locomotive is a 4 6 2?

Under the Whyte notation for the classification of steam locomotives by wheel arrangement, a 4-6-2+2-6-4 is a Garratt or Union Garratt articulated locomotive using a pair of 4-6-2 engine units back to back, with the boiler and cab suspended between them.

The 2-6-6-4 was a fairly late development, a product of the superpower steam concept, introduced by the Lima Locomotive Works, which encouraged the use of large fireboxes supported by four-wheel trailing trucks. Such a firebox could sustain a rate of steam generation to meet any demands of the locomotive’s cylinders, even at high speed.

## How to compare 2 / 6 and 2 / 4 fractions?

Note: When comparing fractions such as 2/6 and 2/4, you could also convert the fractions (if necessary) so they have the same denominator and then compare which numerator is larger. Compare another set of fractions here.
