Bonnie Cars (Boni Cars, platform extender cars)

Post by JimmyMaBoy » Tue Jul 24, 2018 7:11 am

Does anyone have pictures or information of the old Bonnie Cars? Essentially, flat cars used as bridge plates that were set up when track was OOS, to assist in boarding and detraining passengers.

JMB: The term for these platform extension cars was from the Metro-North Commuter Railroad -
They were titled "Boni" cars - for the railroad manager that came up with the idea and designed
them...Post this question at the Metro-North Forum for more information about them...MACTRAXX

Moderator Note: moved to Metro-North. Lemme know if other roads used similar cars though, and if anyone wants to discuss them, we’ll open a new general topic.

The (relatively new) Morning Sun book "Metro North in Color" has several pictures of them on the New Haven Line in the 80s. I thought they were pretty interesting and it made me wonder why they aren't used nowadays, vs bridge plates. I figured bridge plates are more portable and able to set up "on the fly", vs flat cars, which need to be stored somewhere, then brought to the particular station in question where they're needed, etc.

I remember the "Boni" Cars. Ed Boni was the superintendent early on in Metro-North and a good one at that. This was his idea and they were used when the track outage on tracks 3 or 4 was going to be for days at a time for track work. They worked quite well but back then you had railroad people making decisions and not a bunch of political hacks like a lot of it is today.

I remember using them when I commuted to Manhattan in the 80's.
