4-8-0+0-8-4

A 4-8-0+0-8-4, in the Whyte notation for the classification of steam locomotives by wheel arrangement, is a Garratt articulated locomotive. The wheel arrangement is effectively two 4-8-0 locomotives operating back to back.

Other equivalent classifications are:

UIC classification: 2D+D2 (also known as German classification and Italian classification)

French classification: 240+042

Turkish classification: 46+46

Swiss classification: 4/6+4/6

This was the fifth rarest Garratt arrangement, with a total of 26 constructed. All of these were built by Beyer, Peacock for the convert|5|ft|6|in|mm|0|abbr=on-gauge Bengal Nagpur Railway. The first sixteen were designated Class N by the system, and were delivered in 1929; ten more arrived in 1931, classified class NM. [cite web
