Have any one in TS have made Bedford to Bletchley I have merge WCML South and MML London to Bedford it will be good for some on to make it as link up the to route and I have seen freight trains use this route on Real Times Trains
Bedford to Bletchley does indeed exist for TS albeit as a freeware route from UKTS: https://uktrainsim.com/filelib-info.php?form_fileid=36624. However it does require quite a number of various add-ons and third party content. Hope this helps.
