new trainshed roofs covered a southward extension of the station; in addition a large expansion to the east took place, with additional bay platforms there on the north side of the former bays. The original through track was blocked to form east and west bays, so that there were still only three through platform lines. This work was completed in 1894. The new group of bay platforms at the east end had their own concourse quadrangle, known at the time as the "Tynemouth Square". There was a separate booking hall for those local services. At this stage the roof covered seven and a half acres in area; there were fifteen platforms with a length of 3,000 yards. Killingworth Billy In 1901 an early steam locomotive was on display at the station: [The station] is further graced by a pedestal on which stands a curious old locomotive rejoicing in the name of "Billy". The true early history of "Billy" is well-nigh veiled in the mists of antiquity, and it was only by diligent enquiry that Mr Holliday, the Station Master, was able to learn a little of her antecedents. That "she" was constructed as far back as 1824 – 1826 is however certain, and on that score alone she is entitled to an introduction to such of the readers of the Railway Magazine as have until now been unaware of her existence. For about fifty-five years (until 1879) she performed good service, first at the Springwell, and latterly at the Killingworth colliery, from which place she actually steamed into Newcastle in 1881 to celebrate George Stephenson’s Centenary. An image of the locomotive in Bywell's article is captioned "Puffing billy" but it is not Puffing Billy of 1814, which is currently on display at the Science Museum in London. The locomotive in Bywell's article is known simply as Billy (Built in 1826). It was presented to Newcastle upon Tyne Corporation for preservation in 1881. Initially it was displayed on a plinth at the north end of the High Level Bridge, but was moved to the interior of Newcastle Central Station in 1896; it remained there until 1945, when it was moved to the city's Museum of Science and Industry; it was moved again in 1981 to the Stephenson Railway Museum in nearby North Shields, where it is still on display. The early history of the locomotive is uncertain; it is probably a
