LaGuardia reminds me of Quintinshill.

These things happen.

The deadliest rail accident in British history occurred at the Quintinshill signalbox. Day signalman James Tinsley cleared a troop train to enter the control point, completely forgetting that the track was occupied by the local train that he had just got off of.

Responsibility for Quintinshill signal box rested with the stationmaster at Gretna railway station who, on the day of the accident, was Alexander Thorburn. The box was staffed by one signalman, on a shift system. In the mornings, a night-shift signaller would be relieved by the early-shift signaller at 6.00 am. On the day of the disaster, George Meakin was the night signalman, while James Tinsley was to work the early day shift.

At 6.38 am the first of the northbound expresses from Carlisle passed Quintinshill safely. At 6.42 am Kirkpatrick "offered" the southbound troop train to Quintinshill. Signalman Tinsley immediately accepted the troop train, and four minutes later, he was offered and accepted the second northbound express from Gretna Junction. At 6.47 am, Tinsley received the "train entering section" signal from Kirkpatrick for the troop train and offered it forward to Gretna Junction, having forgotten about the local passenger train (aboard which he had arrived that morning), which was occupying the Up line. The troop special was immediately accepted by Gretna Junction, so Tinsley pulled "off" his Up home signal to allow the troop train to run forward.
