Nepojmenovan� dokumentZdravim vsechny,
prekladam dokument tykajici se vysokorychlostni zeleznicni infrastruktury a nejsem si jista spravnym ceskym ekvivalentem uvedenych termin�. Pokud ma nekdo zkusenosti s touto oblasti, budu rada za radu.

1) overthrow
Kontext:
Calculation of OVERTHROW on curves: This section sets out the calculation for the enlargement of a vehicle swept envelope (= prostor vytvo�en� obrysem vozidla) that results from travelling around a curve.
The OVERTHROWS at a point on a vehicle body is the difference between the radial distance from the track centreline to the point (Rdo or Rdi), and the lateral distance from the vehicle centreline to the point (Wo or Wi). This is calculated with the vehicle stationary.

2) Ballast pick-up ("ballast" jako sterk/sterkove loze je mi jasne, jde mi o to "pick-up". Mam sice nize uvedenou definici, ale jestli to ma nejaky odborny termin v cestine, se mi nepodarilo najit)

Ballast pick-up = An aerodynamic phenomenon in which ballast is thrown up or projected ("Schotterflug" v nemcine, "Envol de ballast" ve francouzstine).
