The articulated-body design was not unique to the Crocodiles.
 It was used in the United States on the Milwaukee Road class EP-2 "Bi-Polars", for example.

Many more locomotives adopted the design of long noses without articulation of the body.
The single GE 4/4 of the Yverdon–Ste-Croix railway was known as the "Crocodile", despite being an elongated Bo-Bo steeplecab with articulated bogies beneath, rather than an articulated locomotive.
This extended to painting it with large crocodile heads on each side.

In the United Kingdom, the LNER Class ES1 featured a crocodile-like design and was built between 1902 and 1904, both locomotives remaining in service until 1966, when No.2 was scrapped and No.
1 (BR No.26500) was preserved, now on display at Shildon Locomotion Museum.

The Panama Canal uses double-ended locomotives, known as 'mules', to act as land-based tugs to steer ships through the Canal's lock chambers.

Furthermore, some examples of locomotives similar in design to the Crocodiles, which were manufactured by Škoda can be found on the route between Borjomi and Bakuriani in Georgia.
