To increase the speed on the local railway lines to 50 km/h, the HSM needed stronger tank engines than the existing ones with four driving wheels.

Finally, in 1914, Schwartzkopff built the last successor series that entered service as 1044–1048.

Due to the lower loading gauge on the site of the Blast Furnaces, the chimney was shortened and the front of the smokebox was painted with scare stripes, as is usual with the Hoogovens.

'Bello' is the nickname of steam locomotive NS 7742, which has been in service on various routes in the Netherlands since 1915.

Bello was delivered to the HIJSM by the Berlin factory Schwartzkopff in 1914 and ran as locomotive No.

The locations of the locomotive at that time included Apeldoorn, Winterswijk, Neede, Doetinchem, Uithoorn and Hattem.

Standing still in all weathers proved to be detrimental to its lifespan, so in 1978 the locomotive was sold to the Museum Steam Tram Hoorn-Medemblik for the symbolic amount of one NLG.

On Saturday 13 September, Bello returned to Bergen once more on the occasion of the Open Monument Day 2014 with the theme 'On a Journey'.

For example, there is still a Stationsstraat, and something of the route can still be recognized in the line Dreef – Plein – Berkenlaan – Rondelaan.

The term became a nickname among the public for all small locomotives on local railways and tramways that regularly rang their bell loudly when passing a level crossing or on the side of a road.
