Differences Between Seated Coaches and Sleeper Coaches

[SanLouis]

Coaches are categorized into seated coaches and sleeper coaches based on passenger accommodation. Seated coaches are further classified into large, medium, and small types according to the number of passenger seats. Based on their value and comfort level, large seated coaches are divided into five grades: High Grade 3, High Grade 2, High Grade 1, Medium Grade, and Standard Grade (abbreviated as Large HG3, Large HG2, Large HG1, Large MG1, and Large SG respectively. In reality, large commercial vehicles nowadays rarely include Medium or Standard Grade models). Medium seated coaches are categorized into four grades: High Grade 2, High Grade 1, Medium Grade, and Standard Grade (abbreviated as Medium HG2, Medium HG1, Medium MG1, and Medium SG). Small seated coaches also have four grades: High Grade 2, High Grade 1, Medium Grade, and Standard Grade. Sleeper coaches are classified into three grades: Standard Grade, Medium Grade, and High Grade.
