 Prior to this the Caledonian Railway had intended to apply for powers to subscribe for shares in the CDR and to work it, but a difference of opinion about the connection to the G&SWR lines resulted in the Caledonian withdrawing for the time being.In the 1881 session, however the Caledonian relented and the Caledonian Railway (Additional Powers) Act empowered it to subscribe 50% of the share issue, and to manage and work the line.Only now, on 7 December 1881, did the company issue a prospectus inviting public subscription.
