Recent studies on train passengers’ activities found that many passengers were engaged in some form of work, e.g. reading and writing, while traveling by train. A majority of the passengers reported that they were disturbed by vibrations or motions during their journey. A laboratory study was therefore set up to study how stationary low-frequency lateral vibrations influence the difficulty to read and write. The study involved 48 subjects (24f+24m) divided into three age groups. Two levels of sinusoidal vibrations were applied at nine discrete frequencies (0.8–8.0 Hz). Subjects performed both reading and writing tasks under two sitting positions (leaning against the backrest and leaning over a table). The judgments of perceived difficulty to read and write were rated using Borg's CR-100 scale. The results showed significant differences between the tasks and postural conditions. The subjects reported greater difficulty while reading and writing on the table than while leaning back. The frequencies up to 5 Hz had a particular influence on the perceived difficulty.
