3.2 Quality of railway freight vehicles and infrastructure
SRT (State Railway of Thailand 2002) operates freight service with old locomotive and
wagon. Shortage of rolling stock for freight service is usually experienced. The service age of
locomotive and wagon of railway vehicle are shown in Table 1 and 2, respectively. An old
module of locomotive is shown in Fig. 4. Moreover, many parts of railway track life are
expired. Damaged rail, wood-sleeper and level crossing are often found as shown in Fig 5, 6
and 7, which seriously disturbed the railway operation.
