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. The Caledonian would work and maintain the line for 45% of gross receipts.
