Peto was an experienced railway contractor, responsible for organising railway construction, obtaining all the necessary materials and personnel - engineers, administrators, supervisors, and labour - at the right place and time and delivering the finished product within strict deadlines. He had progressed into railways from the building trade and had worked with Brunel in the 1840s. A visionary loth to refuse any challenge, he had also taken a few knocks along the way, learning from experience to share the constant stress and massive workloads with other wise experienced heads. 1854 found him in partnership with Edward Betts, a gifted administrator, and Thomas Brassey, a like minded entrepreneur, long-time friend of George Stephenson, and whose vast experience of large scale projects helped to keep Samuel's vision within the horizons of the achievable and profitable.
This formidable grouping, known unsurprisingly as Peto, Betts & Brassey, had recently completed the Royal Danish Railway Jutland to Schleswig link in record time, and mid-November 1854 saw Samuel Peto in Copenhagen, to receive the Order of the Danebrog from King Frederick VII for his pains. Credit for planting the seed of the idea for the Crimean railway could arguably go to the Danish Foreign Minister. Just before Samuel set off back to England, he took him aside and informed him that he had just received news from their Constantinople embassy that the British Army was in serious trouble following an immensely destructive hurricane which had wiped out the road communications between Balaklava, now a morass, and the troop encampments, now marooned on the heights with minimal supplies. The implication, unconscious or otherwise, was that a railway was desperately urgently needed to assure the supply of the Army,or it was in danger of perishing. This conclusion formed in Peto's mind during the voyage home and immediately after arrival at Lowestoft on the 22nd, he called on Thomas Brassey to elicit his views.
