This is an infobox for generic electric multiple units and diesel multiple units, as well as carriages.   ব্যবহার  This template has a large number of parameters, some of which, for historical reasons have duplicates that have been deprecated. Please note that parameter names are case-sensitive.  Only one parameter is required:  name - The name that will appear as the title of the infobox. Please do not change the colour of the text here, do so in background below.  The remaining parameters are as follows (in the order that they will appear in the template output):  background - the background colour of name parameter, either as a "colour name" (e.g. forestgreen), a hexadecimal value (e.g. #0093cf), or a colour template (e.g. #). If the background is dark, please change the text colour by appending the CSS color selector. (e.g. background = black;color:white or background = #806040;color:#ffffdd ). Note that quotation marks are not permitted in these CSS statements. If  is present, but blank, the default is white; but if this parameter is omitted entirely, the default background colour is #eee.  image -  The filename for the infobox image.  imagealt - Alternative text for image.  imagesize - The size (width) of the images in pixels (as in imagesize=200). If  is present, but blank the image will appear full size; but if this parameter is omitted entirely, the default size is 229 pixels wide.  caption -  The image caption that will be displayed.  interiorimage - The filename for the second infobox image.  interiorimagealt - Alternative text for interiorimage.  interiorcaption - The second image caption that will be displayed.  service - The dates that the vehicles were in service, separated by an en dash (e.g. 1964–1976).  assembly - where it was produced (city, country)  designer - if another company designed the vehicle  ordernumber      - The Order number or Lot number the vehicles were procured under.  কারখানা      - The factory at which the vehicles were made (if manufacturer had more than one factory).  family       - The type or range of manufacturer’s vehicles that the vehicles comes from (e.g. British Rail Mark 3).  replaced      - The vehicles that were replaced by these vehicles.  yearconstruction - The dates that the vehicles were under construction, separated by an en dash (e.g. 1964–1976). constructed also works  yearservice      - The date that the vehicles first entered service.  refurbishment    - The dates that the vehicles were refurbished, separated by an en dash (e.g. 1964–1976).  yearscrapped     - The dates that the vehicles were scrapped, separated by an en dash (e.g. 1964–1976).  numberconstruction - The quantity of vehicles under construction. construction also works, but is deprecated.  numberbuilt      - The quantity of vehicles manufactured.
