A railway to serve
Deeside was first suggested in 1845. A long line to
Banchory was estimated to cost £95,000, or £220,000 to reach
Aboyne, a distance of . This was authorised by the '
(9 & 10 Vict. c. clviii) on 16 July 1846, but it was decided to wait for the Aberdeen Railway to open first. Shareholders wanted their money back when the railway mania bubble burst, but it survived because the Aberdeen Railway bought a large number of shares. Interest was restored after Prince Albert purchased Balmoral Castle, to which the Royal Family made their first visit in 1848, and the Aberdeen Railway was able to sell their shares. Investors were still hard to find, but by limiting the railway to a line between Ferryhill, in Aberdeen, and Banchory the Deeside Railway was able to apply to Parliament for permission in 1852. Permission was granted in the ' (
15 & 16 Vict. c. lxi), and the railway opened on 7 September 1853. On opening, the terminus of the railway was at
Aberdeen Ferryhill railway station, which was also the terminus of the
Aberdeen Railway at the time. The railway was extended north to a new terminus,
Aberdeen Guild Street, in 1854. A special train with 15 carriages travelled from Aberdeen to Banchory, and public services began the next day. There were three trains a day, taking about an hour to travel the . First class accommodation was available for d a mile, reduced to 1 d a mile for third class. Initially the service terminated in Aberdeen at Ferryhill station, but this was extended to Guild Street when that opened in 1854, the Deeside Railway paying £700 for the first three years and then £1000 a year for the running rights. Initially the Aberdeen Railway operated the services, but only made one locomotive available, so the Deeside decided to buy its own rolling stock, and this was in service by summer 1854. A new company, the Aboyne Extension, was formed to reach Aboyne, and the Deeside agreed to operate services. Instead of building two bridges across the Dee, as had been proposed on 1846, the railway instead took a cheaper but longer route through
Lumphanan. The railway was authorised on 27 July 1857, and services began on 2 December 1859. The Aboyne and Braemar Railway was formed to build a line from Aboyne the to
Braemar. This would follow the Dee, and to cross it from its terminus. However, this was modified during the parliamentary proceedings to terminate at
Bridge of Gairn with the passenger terminus short at . This route was approved in the '''''' (
28 & 29 Vict. c. cclxxix) on 5 July 1865, and opened to Ballater on 17 October 1866. Some work was done on the line to Bridge of Gairn, but remained unfinished. By 1855 there five services a day over the long line, taking between 1 hour 50 minutes and hours. ==Royal services==
