A handful of good prototype solutions photos I located:

The DB Class 66 was a class of two Deutsche Bundesbahn (DB) locomotives created for fast goods train and passenger train services on the major and branch lines of Deutsche Bundesbahn (DB), the national railway of the former West Germany.
The Class 66 had been one of several newly created locomotive classes, the so-named Neubauloks, constructed for the DB soon after the Second Planet War. The 66s had a prime speed of 100 km/h and an axle load of only 15 tonnes which made them ideally suited to such duties. They had been intended to replace the former state railway (Länderbahn) locomotives of DRG classes 38.ten (ex-Prussian P 8), 78 (ex-Prussian T 18) and 93 (ex-Prussian T 14). Nonetheless rising competitors from diesel locomotives meant that no far more engines had been built soon after the two prototype, even even though they completely met all expectations and were a quite productive style. The Class 66 was the penultimate locomotive class to be constructed as portion of the DB’s Neubaulok construction programme.

Aérospatiale-BAC Concorde is a retired turbojet-powered supersonic passenger airliner or supersonic transport (SST). It is one particular of only two SSTs to have entered industrial service the other was the Tupolev Tu-144. Concorde was jointly created and developed by Aérospatiale and the British Aircraft Corporation (BAC) beneath an Anglo-French treaty. First flown in 1969, Concorde entered service in 1976 and continued commercial flights for 27 years.
Among other destinations, Concorde flew standard transatlantic flights from London Heathrow and Paris-Charles de Gaulle Airport to New York JFK, Washington Dulles and Barbados it flew these routes in significantly less than half the time of other airliners. With only 20 aircraft built, the development of Concorde was a substantial economic loss Air France and British Airways also received considerable government subsidies to obtain them. Concorde was retired in 2003 due to a basic downturn in the aviation industry soon after the type’s only crash in 2000, the 9/11 terrorist attacks in 2001, and a choice by Airbus, the successor firm of Aérospatiale and BAC, to discontinue maintenance help.
A total of 20 aircraft were built in France and the United Kingdom six of these had been prototypes and development aircraft. Seven every single were delivered to Air France and British Airways. Concorde’s name reflects the improvement agreement between the United Kingdom and France. In the UK, any or all of the type—unusually for an aircraft—are identified basically as "Concorde", with no an report. The aircraft is regarded by many people as an aviation icon and an engineering marvel.
