// Probably best to loop through each return here and add to a new [], then if another entry supersedes it, overwrite it in the []. Then pass to the below part of the function to process the data for sending.
// Maybe break in to a new function parseTrains() which can take in any dbquery array and remove any services that are not meant to be displayed based on the data provided. Maybe have a date as an input so it can be used in the future to fetch trains for a given date in the future - due to database cleaning in db-manager, past dates would need adjustments to how the database is cleaned leaving outdated services available.
