The "Coffee Pots" were four small engines that worked for the Tidmouth, Knapford and Elsbridge Light Railway. They were designed by Topham Hatt and nicknamed "Coffee Pots" due to the fact they resembled coffee pots and were prone to cough up dirty brown water.
Silas[]
Silas was the first of the Coffee Pots to be built.
Biography[]
Silas was built by Topham Hatt at Tidmouth. He was created out of spare parts to run the line around the headlands to Tidmouth, as the Ulfstead Mining Company were unwilling to spend money on buying an engine despite the line being much too far for horse workings. In his original form, Silas was made up of an old portable engine mounted on a wagon chassis, driven via reduction gearing. This worked for a few years until the boiler wore out, at which point Hatt employed a vertical boiler from a ship's donkey engine on the back end of the wagon chassis. With the portable engine's boiler now just for show, the vertical boiler at the rear was connected up to the portable engine's cylinder, so that the existing drive using the flywheel and reduction gearing could still be used.
Silas had a total of six horsepower and a top speed of six miles per hour. Eventually, the chassis showed signs of coming apart under the strain, and thus a second Coffee Pot was built, with the first being relegated to a spare engine. Upon the railway's amalgamation with the Wellsworth and Suddery Railway to form the Tidmouth, Wellsworth and Suddery Railway, Silas was scrapped.[2]
Technical Details[]
Basis[]
Silas was based on the Coed Talon Colliery locomotive Express, which was built by William Lea in 1874 and worked until the closing of the pit in 1910.
Livery[]
According to Christopher Awdry, the Coffee Pots had no discernable livery as they were forever being dirtied by the coughed-up water.

- Silas was the only Coffee Pot to not survive to the formation of the North Western Railway.
- A drawing of Silas was used by Wilbert Awdry in his lecture as a slide, but it has sadly been lost.
- Christopher Awdry revealed Silas's name through an email correspondence with Sodor Island Models in 2025.[1]
Clarus[]
Clarus was the second of the Coffee Pots to be built.
Biography[]
Clarus was built by Topham Hatt using a new, strengthened chassis design and a ship's donkey engine, as a successor to Silas, who was beginning to fall apart. He could cope easily with one hundred tonnes on the level.
When the Tidmouth, Wellsworth and Suddery Railway was amalgamated in 1912, Clarus and Clifford were kept in reserve and worked on the line between Knapford and Elsbridge, while the engines of the Wellsworth and Suddery Railway worked its main line. Both Coffee Pots would later pass into the ownership of the North Western Railway in 1915. By 1919, they - like the former Wellsworth and Suddery Railway engines - are said to have been in very poor shape.[2]
Between 1924 and 1925 the branch line was extended to Ffarquhar and its quarry, but the "Coffee Pot" engines were not deemed adequate for the haul. After a probationary period at Wellsworth, Thomas was transferred to take charge of their branch line. The "Coffee Pots" continued to serve the line as back up, though their limited braking abilities on the steep Quarry Tramroad sometimes caused the heavy stone trains to run out of control.
The "Coffee Pots" were withdrawn from service and eventually scrapped around the 1950s. They were not very well documented, and were never even photographed but a reference is made to them by Ffarquhar's Stationmaster, Kevin Volley. In his letter, it is revealed one or another were still operating during the event of Thomas and his crew being fined for illegally operating on the tramroad extension. Their actual scrapping date is not mentioned but their remaining importance would have been further diminished when Toby arrived in 1951 and took over the quarry's operations.
Technical Details[]
Basis[]
Slides from the Railways of Sodor lecture suggest that Clarus would have looked similar to one of the three vertical-boilered tank engines built by Penrhyn-based firm Sara and Burgess for use at Falmouth Docks in the 1860s. A similar engine was built by the same firm in 1912 for the Port of Par and was in service until 1927, its boiler later being mounted onto the chassis of its co-worker, Manning Wardle E Class 0-4-0ST "Punch", in 1932.
Livery[]

Clifford[]
Clifford was the third of the Coffee Pots to be built.
Biography[]
Clifford was built by Topham Hatt to a similar design as Clarus, however with an enclosed design for a roadside tramway passenger service on a newly-opened extension to Elsbridge in 1910.
When the Tidmouth, Wellsworth and Suddery Railway was amalgamated in 1912, Clifford and Clarus were kept in reserve and worked on the line between Knapford and Elsbridge, while the Wellsworth and Suddery Railway engines worked its main line. Both Coffee Pots would later pass into the ownership of the North Western Railway in 1915. By 1919, they - like the former Wellsworth and Suddery Railway engines - are said to have been in very poor shape.[2]

The "Coffee Pots" continued to serve the line as back up, though their limited braking abilities on the steep Quarry Tramroad sometimes caused the heavy stone trains to run out of control.
The "Coffee Pots" were withdrawn from service and eventually scrapped around the 1950s. They were not very well documented, and were never even photographed. The stationmaster, Kevin Volley, revealed one or another were still operating during the events of 'Thomas in Trouble. Their actual scrapping date is not mentioned but their remaining importance would have been further diminished when Toby arrived in 1951 and took over the quarry's operations.

Basis[]
Clifford is of a freelance design, therefore he is not based on any specific real-life engine.

According to Christopher Awdry, the Coffee Pots had no discernable livery as they were forever being dirtied by the coughed-up water.

Conrad[]
Conrad was the fourth of the Coffee Pots to be built.
Biography[]
Conrad was built and designed by a young Sir Topham Hatt, when he was an engineer to the Tidmouth, Knapford and Elsbridge Railway.
Following the railway's amalgamation in 1912, Conrad was later used by the North Western Railway to pull trucks from Anopha Quarry, but was worn out soon after Thomas was given charge of the Ffarquhar Branch Line.
The "Coffee Pots" would be withdrawn from service and eventually scrapped around the 1950s. They were not very well documented, and were never even photographed, although the fourth engine would be recorded in The Island of Sodor: Its People, History and Railways.
