    WebElement scroll = driver.findElement(By.xpath("//div[@id='gvLocationHorizontalRail']"));
    JavascriptExecutor js = (JavascriptExecutor)driver;
    js.executeScript("window.scrollBy(250,0)", "");

Answer 1

You are using javascript that scrolls the main window, if you want to scroll a element, you should first get the element by id, then change the its scrollLeft property:

JavascriptExecutor js = (JavascriptExecutor)driver; 
js.executeScript(
    "document.getElementById('gvLocationHorizontalRail').scrollLeft += 250", "");

If you instead want to change the scrollbar that moves up and down, you should change the scrollTop property.

In addition to answer by Ferrybig, can you try this:

WebElement scroll = driver.findElement(By.xpath("//div[@id='gvLocationHorizontalRail']"));
JavascriptExecutor js = (JavascriptExecutor)driver; 
js.executeScript(
driver.execute_script("arguments[0].scrollIntoView()", scroll);
