As it also saturate my 8Gb of RAM). What I observe is a bigger graph too (it seems to double).\r\n\r\nIs that expected?\r\n\r\nAs a workaround, I currently enabled the option to use the transfers.txt file, but as it's not available on all the GTFS datasets I use, and as when its available the coverage is not perfect, I would prefer use OTP linking system."}}
