There has been considerable publicity in recent days to do with the proposed new Ashland station. Most of the discussion has been to do with the appearance of the station and its impact on the college’s activities. But there may be some engineering issues to consider also. For example, one commenter noted that freight cars are wider than passenger cars. Therefore freight traffic will not be able to travel through the station.
I took a quick look at this issue. Regarding the width of cars the following dimensions apply.
- Amtrak standard car 119.5”.
- Freight car dimensions vary but it appears that most box cars are 128” wide.
Hence the difference between the in width between passenger and freight cars is 8.5”. Given that the extra width projects to both sides of the car it would appear that running a freight train through the new station would require that the gap between the platform’s edge and the passenger car door would have to be at least 4.25″ greater than required for just passenger service. This is a considerable distance and presumably would not meet wheelchair requirements.
Therefore my tentative conclusion is that the only way the new station would work would be for CSX to create at least two bypass lines for the freight trains. In other words the new station forces a third rail to be installed. This would do more damage to college life than would the new station.
I presume also that they could not apply a “minor upgrade” to the existing station for the reasons discussed to do with the tracks themselves — as soon as the project engineers touch the tracks and station all grandfather exemptions disappear.
If anyone has knowledge of railroad engineering standards please let me know if this conclusion is correct.
