The introduction of the new D class further displaced the class.

Seven members of the D class have been preserved, although only two are in operational condition.

Which was why it had been quickly bested and replaced by the D class.

D class was also the first class of British submarine to have standard radio fitted.

The D class was introduced for suburban passenger service in 1912.

Thus there was no "feelings" of being in the "D" class.

There is no clear reason why the class was named the D class.

The D class never really got off the ground in earnest.

The D class were originally built as 2-4-0s between 1880 and 1887.

It is significant as the first of the D class to have been built.
