This project was created to develop Railroad intersection projection mappingmedia and evaluating the satisfaction of the audiences understanding about Railroadintersection projection mapping media. evaluated by 100 sample size who answer thequestionnaires to collect data. The statistics in data that was used for analysis isfrequency percentage mean and standard deviation. This evaluating result is targetgroup are satisfied with The Railroad intersection projecting mapping media in high level. (𝑥̅= 4.56 SD = 0.59)

The objectives of this special project were to develop printed media for public relations in the form of Augmented Reality books and to evaluate the appropriateness of printed media for public Make Collecting data from advertising and public relations officers The State Railway of Thailand 10 people and 15 grade 6 teachers statistics used in data analysis were frequency percentage mean and standard deviation. The results showed that 1) has created the media print Railroad Cut Point Augmented Reality 2) The media is appropriate and is distributed to the public at the highest level. (𝑥̅= 4.50 SD = 0.50).

Presently the rail transit system plays a major role in the commercial world that they currently use diesel engine not only causing to a lot of fuel consumption but also generating numerously pollution. Therefore this project aims to study the break-even point of investment under comparison of brake specific fuel consumption and pollution of locomotive engines. By experimental works there are 3 types of locomotive engine: Pielstick M.T.U. and Caterpillar which are the difference of the combustion chamber and the fuel injection systems. The simulation load on the static tests (Dynamometer) was used following the regulation characteristic curve which is standard of State Railway of Thailand. As a result of testing the engine using common rail type of fuel injection system M.T.U. was the lowest brake specific fuel consumption at all of engine by the average of all engine speed 206 g/kW-h of brake specific fuel consumption. It is lower than Caterpillar (Semi common rail with direct injection) which is 314 g/kW-h equivalent 34.39 % while Pielstick engine a mechanism fuel injection system is 389 g/kW-h equivalent 47.04 % For pollution area there are Hydrocarbon (HC) Nitrogen Oxide (NOX) and black smut. The engine with direct injection system relieved the previous substance less than the pre-combustion engine. Moreover the compound of carbon monoxide (CO) was found that the pre-combustion engine (Pielstick) discharged carbon monoxide (CO) less than the direct injection engine (Caterpillar) whereas the common rail engine emancipated same substan cenear by with the pre-combustion engine (Pielstick). However the new technology of the engines is high maintenance costs. Therefore a number of applications have to be needed to make a quantitative value for the investment.
