The steam motor service between London and Redhill was only an experiment, and the horse-drawn vehicle maintained its old position on that route until 1902, when the improvements in motors justified the Post Office in starting a motor service. Since 1902 the London and Redhill service has been performed by motors. Since 1905 the Brighton service has been worked by motor van, the daily journey there and back being 109 miles. In the following year motor vans ran to Hastings, Tunbridge Wells, and Eastbourne. Then followed in three succeeding years new motor services to Ipswich, Southampton, Cambridge, Reading, Portsmouth, Oxford, Birmingham, Stony Stratford and Leicester, Tilbury, Aylesbury, Dover, and Ramsgate. In addition there were cross services between Manchester and Liverpool, Birmingham and Warwick and Worcester, Leeds and York, and a number of other places. The distance covered by Post Office motor vans runs into several thousands of miles daily. Motor vans can travel much faster than the old four-horse coaches. Palmer's idea of the ultimate speed of the mail coach was 10 miles an hour. This speed was often attained before 1840, but no doubt the average all over the country was more like 7 or 8 miles an hour. And this was the average speed of the Parcel Post horse-drawn coaches. The usual rate of the motor coaches is 10 miles an hour. Another advantage claimed by motor vans compared with horse-drawn coaches is that they can carry heavier loads. The larger night vans can take a load of 2¼ tons as compared with 1½ tons, the carrying capacity of the old horse coaches. Most of these motor mail coaches travel during the night. In the case of the long-distance services, such as London and Brighton, two vehicles are used, starting from each end of the journey, meeting half way. It is remarkable how little the place of meeting varies each journey. De Quincey, in a footnote to his essay on _The English Mail Coach_, remarks upon this same feature in the early years of the last century. “One case was familiar to mail coach travellers when two mails in opposite directions, north and south, starting at the same minute from points six hundred miles apart, met almost constantly at a particular bridge which bisected the total distance.” These night motor coaches are timed to arrive at their destination so that the mails conveyed can be distributed by the first morning delivery. A guard accompanies most of the coaches, and in addition to looking after the safety of the mails and assisting in loading and unloading, he sorts parcels received from places _en route_ for places served by the coach. These vehicles serve, therefore, a similar function to the Travelling Post Office. The guards used to carry arms for defence in case of attack, but they are now only supplied with a truncheon and whistle.
