The railway was held back by the available budget, and by 1903 Manor Asylum, Horton Asylum, the associated power station and the Ewell Epileptic Colony (later known as St Ebba's) had all been completed. Work was about to begin on the large Long Grove Hospital, and the issue of road damage got worse. In 1904 LCC decided to issue an umbrella contract, and this enabled the contractor to lay a railway.
Due to budgetary limitations, the railway project faced delays. By 1903, Manor Asylum, Horton Asylum, the power station, and the Ewell Epileptic Colony (later known as St Ebba's) were completed. Construction on Long Grove Hospital was imminent, while road damage became a growing concern. In 1904, LCC issued a broad contract to overcome these obstacles and allow for railway construction.
