RAIL ATLASby Train Life0-4-0ST
Prince belongs to the Ffestiniog Railway in Wales. It is a small steam engine built for a narrow-gauge railway, where the rails are closer together. Its separate tender carries extra supplies.

Heat turns water into steam. Steam pushes pistons, and rods turn the wheels. Explore the boiler, cab, running gear and supplies.
Hot gases pass through the boiler and into the smokebox before leaving through the chimney. Look underneath: a curved support called a saddle holds the front on the locomotive’s frame.

The crew works here. On a conventional steam locomotive, the fireman tends the fire and the driver controls the engine.
A locomotive’s cab is a workplace, not a passenger compartment. Some early engines had little shelter for their crews.
The chimney carries exhaust away. Steam domes help collect steam above the water in the boiler.
Steam and smoke are different: steam is water vapour, while smoke comes from burning fuel. Equipment varies by locomotive.
Steam pushes pistons. Rods transfer that motion to the driving wheels, and coupling rods link driving wheels together.
Large wheels suit faster running; smaller wheels and a short wheelbase can suit tight curves and heavy work. Watch the fixed-length connecting rod turn while the crosshead slides in a straight line. This illustrates the outside mechanism; exact cylinder and valve-gear layouts differ between engines.
A steam engine needs water and fuel. Tank engines carry supplies on the locomotive; many other engines pull a tender.
The model shows the general storage area. Tender and tank capacities are not reproduced to engineering dimensions.
Steam pushes pistons, and connecting rods turn the driving wheels.
The wheels grip the rails to move the train. Passenger engines and small yard engines have different jobs: maximum speed is not the only measure of a good locomotive.
Built in 1863.
The Ffestiniog Railway records Prince as the first steam locomotive used by the preservationists on the reopened railway in 1955.
We leave gaps visible instead of guessing. The original catalogue and our learning model do not establish every real-world specification.
The catalogue connects this train with Wales, United Kingdom. That may be where it worked, rather than the factory that built it.
A train uses different materials for different jobs: metals for strength, glass for windows and insulating materials around wires. Paint colour cannot tell us whether the body underneath is steel or aluminium.
Known background: Wales, United Kingdom. Its job: narrow-gauge railway work. A country name alone does not tell us which line it used.
Old photographs and launch announcements do not prove that a train still runs. A whole class may still work even after one member retires. We need a recent operator or museum source.

Burning fuel supplies heat.
Heat turns water into steam.
Steam pushes; rods transfer the motion.
The wheels grip the rails.
0-4-0ST uses wheel counts: 0 leading wheels, 4 driving wheels and 0 trailing wheels. Count both sides together. A T means tank engine; ST means saddle tank and WT means well tank.
The driving game uses an approximate simulation speed. It is not a measured or documented speed for this locomotive.
A fast train is a whole system: vehicle, track, electricity or fuel, brakes, signalling and trained people. A race in the game is a simplified comparison.
No. Smoke comes from burning fuel. Steam is water in its gas form. The white cloud you can see contains tiny water droplets formed as water vapour cools.
No steering wheel is needed to choose a direction. The rails guide the wheelsets. At a junction, movable sections of rail called points or switches guide the train onto another track. The driver controls speed and braking.
A moving train has energy. Brakes must remove that energy to slow it down. A heavy train travelling fast needs room to stop, so railway signals help keep trains safely separated.
Compare how they look, what they carry and where their power comes from.
A frame holding wheelsets beneath a vehicle. It can turn relative to the body to help the train follow curves.
The distance between the inside faces of the two running rails. Narrow gauge means closer rails; loading gauge describes the space a train may occupy.
A folding roof collector that stays in contact with an overhead power wire.
The force used to pull or propel the train. Grip between wheels and rails limits how much force can be used.
A train with propulsion equipment within its passenger vehicles, operated together from one cab.
A powered vehicle whose main job is to move other railway vehicles.
Moving and arranging vehicles in a yard, often at low speed.
The colours, stripes, logos and other markings painted or applied to a train.
The permitted speed for passenger or freight operation on a suitable section. It is not the journey average.
A speed achieved on a particular test or record attempt, sometimes with special equipment and conditions.
A vehicle coupled to a steam locomotive to carry extra water and fuel. A tank engine carries water on the locomotive itself.
An early vehicle built to develop and test a design before a production fleet.

Portraits and 3D models are illustrations, with simplified parts and proportions. This is an independent learning guide, not an operator’s timetable.
