While online surveys are considered to be the viable alternative to face-to-face and telephone surveys, many clients express a strong concern about the possibility of unreliable responses. Given this concern, survey experts hypothesize that amounts of time on responding can represent the extent to which respondents fill out the questions with sincerity. This study examines this hypothesis using data from an online survey sample of 1.052. Results strongly suggest that while "long time" informants are reliable, "short time" informants are not. Those in the short time group spend only 2.4 seconds per question and show very different patterns of responses to 49 Likert -typed questions. Logistic regression results imply that these unreliable respondents are interested in monetary gifts and maybe as a result, participate in surveys much more frequently. In conclusion, we provide some implications of these results to the quality of online surveys.

Brake system in railway train operates to reduce the speed of the train or to stop the train via changing the kinematic energy into heat energy for emission and so brake system makes an important rule to transport passenger and cargo for safety operation. Recently operators have a matter of grave concern for the verification of performance in brake system. To verify the exact performance of brake system, most of brake test has been carried out on real operating track condition. Therefore we will determine the braked weight of indirect brake system applied in Iran DMU(Diesel Multiple Unit) in accordance with mc leaflet 544-1, which is to enable Iran DMU to achieve the required braking distances in defined situation.
