HISTORY

Picture
Industrial Service
​ Built in 1958 by Ruston & Hornsby and numbered 421418. It was purchased for service at the Tioxide factory in Grimsby. Tioxide was a chemical factory, with the loco shunting supplies around the site.

Working at Tioxide for all of its life, the loco was donated to the nearby Lincolnshire Wolds Railway along with the other remaining locos.

​It  stayed there for a number of years until being purchased by a volunteer at Telford Steam Railway. 421418 arrived on 20th May 2025.

Donor Loco

The loco is currently going to be used as a donor loco, however it is planned for a full restoration in the future. Believed to be in good mechanical condition, the idea is for Tonka's parts to be used to keep its sister 88DS Hector running when it suffers a failure. The broken part will then be fixed and fitted back onto Tonka.

Tonka is a really useful asset in order to keep Hector in service which is essential for keeping the railway running. Hopefully Tonka will return to service in the future, with its cosmetic condition being the biggest problem to overcome

CURRENT STATUS

Tonka is currently hidden away in a siding at Spring Village. 

The loco hasn't received much attention since arrival but has been sheeted to protect it from the elements. When time allows, a full mechanical inspection of the loco will take place and an attempt may be made to start it. 

The loco does make the occasional public appearence, such as at our Diesel Gala, on static display.

SISTER LOCO 'HECTOR'

Tonka is owned by the group who also have 'Hector'

They are identical loco's appart from the lack of side weights on Tonka, whereas Hector is the 20 tonne version.

Tonka will be used to help keep Hector in traffic for many years to come.
