Twelve identical wagons delivered from the Swansea Carriage & Wagon Co., Ltd., for the opening of the Manx Northern Railway in 1879, these were the first freight vehicles supplied and therefore numbering began with No.1.  These wagons were of a similar design to those supplied, beginning with H.1, to the Railway Company  though they were not supplied with brakes as delivered, these were fitted within the first couple of years, as were heavier leaf springs with nine leaves opposed to the original eight.

This was the first of two batches of wagons inherited from the Manx Northern Railway, the second being Hr.39 - Hr.45 which were constructed by Hurst-Nelson & Co., of Motherwell in 1900 and supplied with bogie carriages No.16 and No.17, later to become F.37 and F.38.  Upon the merger of 1905 all of these wagons were inherited by the Railway Company who re-numbered them to be sequential with their extant three-plank wagons beginning with Hr.27 (the small “r” prefix being common to denote former Manx Northern stock across the fleet).

Falling out of use in favour of the more versatile drop-side wagons, the first to be disposed of was Hr.31 as early as 1924 with the remained being written off the rolling stock records up until the final survivor which was Hr.37 in 1962.  Of note, Hr.36 (then No.10) was damaged in a severe shunt at Ballaugh Station in 1885 owing to defective brakes but was subsequently rebuilt.  They saw heavy used by the Isle of Man Mining Company in their earliest days, often loaded beyond their capacity.
