was as follows: 65 units of class 420 (of which 55 plantations and 10 reserves) and 100 units of class 423 (including 93 plantations and 7 reserves). Until autumn 2014, the class 420 were replaced by modern vehicles of the DB 430 series. This is part of the contract that RMV signed with Deutsche Bahn in November 2011 following the tendering of transport services. Since the completion of the delivery, 100 vehicles of the class 423 and 91 vehicles of the class 430 are in use, the latter vehicles on the lines S1, S7, S8 and S9. Class 420 In the early years trains of the second and third series of electric locomotive class 420 in the color pure orange / Kieselgrau (contrary to original plans, the proposed paint carmine / kieselgrau was not used) were used in Frankfurt, although occasionally lent to 1990 due to lack of vehicles also from Munich blue white 420s were used, for example, the opening of the trunk line extension to Frankfurt South. The cars of the 2nd construction series were delivered completely to the S-Bahn Munich until the beginning of the 2000s. Due to the ever-increasing vehicle demand at that time were between 1980 and 2004 at irregular intervals all railcars of the third and fourth series and numerous cars of the fifth and sixth series from the S-Bahn Stuttgart delivered to Frankfurt. In 2003 began the delivery of new class 423 railcars in Frankfurt, in parallel, in August 2003, the first ET 420 were retired. As of 2004, Frankfurt ET 420 no longer received any main examinations; this was only in 2007 with 420 271 started when it became clear that the delivery of the last railcar due to registration problems would have to be postponed indefinitely. All Frankfurt vehicles were also from 2007 to 2008 for three million euros, a modernization in the interior, which included light gray instead of striped partitions and new upholstery in the current design. At the same time, the already quite advanced phasing-out was severely curtailed and henceforth focused on the railcars of the third construction series in order to be able to take at least the oldest vehicles out of service. Two railcars received the test LED headlights, but these could not prevail in Frankfurt. The rapid-transit railway Rhine Main had the first completely traffic-red vehicle park of the German course AG. This status was
