Introduction of the Argo Lawu (1996 - 2002) The Argo Lawu was launched on 21 September 1996 with the additional brand "JSO-751" which means "Jakarta–Solo traveled for 7 hours on the 51st anniversary of the independence of
RI". At the beginning of its launch, this train operated using a train set made by
PT INKA in 1996 which had the characteristics of using air conditioning with a trapezoidal external unit, lower glass position, and a higher train size. At the same time, this train was also pulled by
CC203, the same as other Argo trains. This train set was the result of intensive health care—including replacing the
bogie with a K8 (NT-60) bogie—from the economy class trains of the 1950s. The Argo Lawu train is the third Argo class train to be launched, after the
Argo Bromo JS950 train and the
Argo Gede JB250.

Taksaka and Argo Dwipangga train. These train sets had a different design from the train sets on the Argo Bromo Anggrek and Argo Muria, namely purple. The geographical conditions on the central Java line that did not match the capabilities of the K9 bogies caused the Argo Lawu train to frequently Derailment (train).

Cirebon and
