Monorail is a type of LRT that a train, made with $2{\sim}4$ cars runs on single track. Monorail can be divided into two types - straddled type, running on track beam and suspended type, running suspended from track beam. After Wuppertal, world's first monorail in German, many monorails are currently operated in Australia, U.S.A, Japan etc. In macountry, it was decided to introduce monorail to 3rd line of Daegue. Daegue's 3rd line is public financial project and supported about 60% of total project cost by central government. The central government announced a standard for rubber-wheel type LRT and steel-wheel type LRT. It becomes a guide to local government willing to introduce this type of LRT. The standard for monorail hasn't announced yet although the necessity of research has grown. Korea Railroad Research Institute which has been asked to research by Ministry of Land Transport and Maritime Affairs has carried out research on standard of monorail considering domestic condition. The on-going research is described in this paper. We wish that it becomes national standard and a good guide for local government.

In the railroad rolling stock depot, long-term maintenance tasks is done regularly every two or four year basis to maintain the functionality of equipments and rolling stock body or for the repair operation of the heavily damaged rolling stocks by fatal accidents. This paper addresses the computer simulation model building for the rolling stock maintenance shop for the CDC(Commuter Diesel Car) and Generator Car planned to be constructed at Daejon Rolling Stock Depot, which will be moved from Yongsan Rolling Stock Depot. We evaluated the processing capacity of two layout design alternatives based on the maintenance process chart through the developed simulation models. The performance measures are the number of processed cars per year, the cycle time, shop utilization, work in process and the average number waiting car for input. The simulation result shows that one design alternative outperforms another design alternative in every aspect and superior design alternative can process total 340 number of trains per year 15% more than the proposed target within the current average cycle time.
