Thank you for your early response. And I appreciate your cooperation for my paper. Apologize that some my question is unclear. Some unclear question should be made clear with you. I tried to clarify them as follows. So I appreciate if you could answer them in this 1week. Because my finale presentation will be soon. Q1: How do LU estimate platform width where including stairs in island platforms? Please see section 3.7.7.1 in the attached document - Island platform widths shall be calculated by treating them as two separate platforms and adding the two widths together. Is the estimated value smaller than the value estimated by the general block? We are not clear what you refer to here. Please see the attached document which should answer your questions. -> This unclear was made clear be by your next answer (special rules for near the stairs). Thank you. Are there any special rules for near the stairs? No, but stairways and escalators feeding directly onto a platform shall be aligned along the length of the platform, i.e. parallel with the tracks. Q3: Among the stations that have recently been upgraded or built, are there any stations that could not be designed with the target LOS? Yes. -> Does your answer mean follow? - In case of the new station could not be designed with target LOS, it designed minimum size written in the standards. Q4: Could you tell me the station designed by this guidance? The attached document is a standard as opposed to a guidance. The two new Northern Line Extensions are probably closest to full compliance with the standard. Also, could you give me a document with specific input and output values at the station actually designed in this guidance? We are not clear what you refer to here. Please see the attached document which should answer your questions. -> What this part means is “Could you give an example of station capacity calculation by this standard". I appreciate if you could send me some calculation example.
