The study objectives were to 1) compare the personal characteristics and training effectiveness of traffic operation officers employed by the State Railway of Thailand (SRT), 2) study the influential factors regarding the training effectiveness of traffic operation officers, and 3) develop and test a causal model of training effectiveness. The research population was selected as traffic operation officers who operated in the Northern route and participated in SMART Station seminar workshop training program for fiscal year 2012-2015 consisted of 320 trainees. A questionnaire survey was employed as the research instrument. Statistics utilized to test the hypothesis and the causal model of training effectiveness of traffic operation officers with empirical data included 1) frequency, percentage, mean, standard deviation, maximum, and minimum, 2) nonparametric methods by the Kruskal-Wallis H test, 3) simple regression analysis, and 4) path analysis based on multiple regression analysis.

Results indicated that 1) traffic operation officers employed by the SRT with different personal characteristics had no different training effectiveness, and 2) influential factors regarding training effectiveness of the traffic operation officers included trainee characteristics, career and job attitude, attitude toward training, organizational characteristics, training design, and trainee motivation. These variables affected training effectiveness at 15.0, 37.0, 39.2, 54.6, 56.1 and 48.1 percent respectively. 3) Testing the causal model of the training effectiveness showed that the  = .8728,  = .8707, Q = .9837, W = 3.253 and = 5.991 indicating that the model fitted with the empirical data.
