By this time the service life of the Class 26 locomotives was coming to an end.

Of the 15th class locomotives, numbers 386, 394 and 395 were the last in use.

The main picture and the following show both sides of the Class 10 locomotive.

These are generally worked by 071 and 201 class locomotives.

In 1980 it was back put into service as a standard class 51 locomotive under number 5101.

Only seven Class 49 locomotives were eventually placed in service.

They were larger than any of the previous 6th Class locomotives.

The seven Class 6 locomotives in this group were numbers 402, 403, 406, 417, 421, 423 and 436.

The 46 class locomotives were involved in a number of serious incidents.

Until the 1970s, these services were hauled by class 01.10 locomotives.
