Meitetsu 7500 series

The Meitetsu 7500 series was a Japanese limited express electric multiple unit operated by the Nagoya Railroad (Meitetsu) from December 1963 to August 2005.
==History==
The 7500 series sets were a higher-performance version of the 7000 series sets. These were designed as a new type of Panorama Car with higher performance and higher functionality. Nippon Sharyo was tasked to build the sets with the first sets introduced in December 1963. Although the sets were dogged with problems regarding the control systems the high speeds of the trains won praise from drivers.
Configurations of the sets changed numerous times over its time in service. Refurbishment began in 1988 but was aborted shortly after, with sets beginning to be retired and scrapped; equipment from these sets would then be reused on the 1030, 1230 and 1850 series sets. Meitetsu then decided to introduce barrier-free measures by raising the platform height; this made the 7500 series sets incompatible with the new barrier free measures as the company deemed that entering and exiting the train would be dangerous due to its lower floor. Retirements and scrapping resumed in December 2004; the last sets were retired in August 2005. No special runs were held to mark their retirement; no 7500 series cars have been preserved.
==Design==
The 7500 series sets use a curved front end with side-mounted headlights in ovoid casings. The 7500 series sets feature a raised driver's cab to allow passengers to have a panoramic view ahead; this cab is accessed via a raised door on the side of the cars accessed via step ladders. The design of the sets is largely identical to that of the 7000 series sets, although the roof of the 7500 series sets is lower than the 7000 series sets, giving the illusion that the cabs protrude more. This is the only discernible difference between both train types.
==Specifications==
Construction was of steel. The trains used resistor-controlled traction systems.
The headlights were somewhat unique in that the casings hide a multi-functional system, allowing the headlights to function as taillights by dropping a red filter over the lamps themselves. The headlights also could act as Mars lights. The top of the cars featured a convex lens mounted on the roof named the "front eye", allowing the driver to see the situation just ahead of the observation seats, although the view is upside down for certain areas and angles. This was the same device as used on the 7000 series sets.
The trains feature a musical horn which produces a modulating tone using a transistor oscillator circuit; initially the horns were branded the "transistor horn" to showcase that they used the latest technology.
